SRv6 VPN commands
bfd static evpn-vpws-srv6
Use bfd static evpn-vpws-srv6 to create a static BFD session for SRv6 PW connectivity detection in an EVPN VPWS over SRv6 network and enter static BFD session view, or enter the view of an existing static BFD session.
Use undo bfd static to delete a static BFD session and all settings in static BFD session view.
Syntax
bfd static session-name evpn-vpws-srv6 interface interface-type interface-number remote-peer remote-ipv6-address [ discriminator auto ]
undo bfd static session-name
Default
No static BFD sessions exist.

Parameters
session-name: Specifies the name of the static BFD session, a case-sensitive string of 1 to 64 characters.
interface interface-type interface-number: Specifies a Layer 3 interface mapped to a cross-connect. The interface-type argument represents the interface type and the interface-number argument represents the interface number.
remote-peer remote-ipv6-address: Specifies a remote PE by its IPv6 address.
discriminator auto: Enables the device to automatically assign a local discriminator value to the static BFD session. If you do not specify the keywords, you must use the discriminator command to specify the local and remote discriminators for the session.
Usage guidelines
Enable BFD on both ends of an SRv6 PW for quick link connectivity detection. The PEs periodically send BFD control packets to each other out of the Layer 3 interfaces mapped to the cross-connect of the SRv6 PW. A PE sets the PW state to Down if it does not receive control packets from the remote end within a detection interval. To avoid packet forwarding failure, the PE switches packets to the backup SRv6 PW or an equal-cost SRv6 PW.
Make sure the static BFD session is in Asynchronous mode.
Use this command on both PEs at the two ends of an SRv6 PW.
In a primary/backup SRv6 PW scenario or an equal-cost SRv6 PW scenario, you must configure a static BFD session for each SRv6 PW to detect their connectivity.
Examples
# Create a static BFD session named abc to test the connectivity of the SRv6 PW associated with a cross-connect mapped to Ten-GigabitEthernet 2/0/0. The IPv6 address of the remote PE is 20::1.
<Sysname> system-view

Table 1 Command output
Field |
Description |
Link ID |
Link ID of the SRv6 tunnel on the VSI or cross-connect group. |
Type |
Route recursion mode. After the PE receives a customer packet destined for an End.DX2, End.DT2M, or End.DT2U SID, it forwards the packet according to the route recursion mode. · BE—SRv6 BE mode. In this mode, the PE first encapsulates the End.DX2, End.DT2M, or End.DT2U SID into the packet. Then, the PE searches the IPv6 routing table based on the SID encapsulated in the packet to forward the encapsulated packet. · TE—SRv6 TE mode. In this mode, the PE first searches the tunnel policies for a matching SRv6 TE policy based on the next hop of a matching route. Then, the PE adds an SRH to the packet. The SRH includes the End.DX2, End.DT2M, or End.DT2U SID and the SID list of the SRv6 TE policy. Finally, the PE forwards the encapsulated packet through the SRv6 TE policy. · BE/TE—SRv6 TE and SRv6 BE hybrid mode. In this mode, the PE preferentially uses the SRv6 TE mode to forward the packet. If no SRv6 TE policy is available for the packet, the PE forwards the packet in SRv6 BE mode. |
State |
SRv6 tunnel status: · Up—The SRv6 tunnel is up. · Down—The SRv6 tunnel is down. · Blocked—The SRv6 tunnel is a bakup tunnel. Its tunnel interface is up, but the tunnel is blocked because the primary tunnel is operating correctly. |

prefix-list prefix-list-name: Specifies an IPv6 prefix list by its name, a case-sensitive string of 1 to 63 characters. If you do not specify this option, the system performs SBFD on all locators which are the recursive nexthops of routes.
Usage guidelines
Application scenarios
In the IP L3VPN over SRv6 BE, EVPN L3VPN over SRv6 BE, or public IP over SRv6 BE scenario, with FRR enabled on a local PE, the PE can use the backup path upon failure of the primary path when a peer CE is dualhomed to two PEs. For fast traffic switchover to the backup path when the primary path fails, configure this feature on the local PE to detect connectivity of the SRv6 locator advertised by the peer PE through BGP.
Operating mechanism
SBFD uses the following procedure to detect connectivity of SRv6 locators advertised through BGP:
1. The initiator (local PE) sends an SBFD packet with the destination IP address as the network segment for the SID identified by an SRv6 locator.
2. Upon receiving the SBFD packet, the reflector (peer PE) identifies whether the discriminator in the packet is consistent with the local discriminator. If they are consistent, the reflector sends an SBFD response to the initiator through IPv6 routing. If they are inconsistent, the reflector discards the SBFD packet.
3. The initiator switches to the backup path if it does not receive an SBFD response before the timeout timer expires. If it receives an SBFD response before the timeout timer expires, the SRv6 locator is reachable.
Restrictions and guidelines
For this feature to take effect, perform the following tasks:
· Execute the sbfd destination ipv6 remote-discriminator command on the local PE to associate the destination IPv6 address of the detected path with the remote discriminator of the SBFD session for the initiator.
· Execute the sbfd local-discriminator command on the peer device of the main path to set the local discriminator for the reflector and make sure the discriminator is consistent on the local PE and peer PE.

Parameters
nexthop-ipv6-address: Specifies a next hop by its IPv6 address.
interface-type interface-number: Specifies an output interface by its type and number.
Usage guidelines
This command is applicable to the IPv6 MPLS L3VPN over SRv6, IPv6 EVPN L3VPN over SRv6, or public network IPv6 over SRv6 scenario to accelerate traffic forwarding. This command allocates an End.DX6 SID to the specified next hop for BGP IPv6 routes and associates the next hop with an output interface.
Use one of the following methods to allocate End.DX6 SIDs to next hops:
· Use this command to dynamically allocate an End.DX6 SID to a next hop from the locator applied to the VPN instance or public instance.
Make sure the output interface specified for the next hop in this command is consistent with the output interface of that next hop in the routing table. If they are inconsistent, the device cannot dynamically allocate an End.DX6 SID to the next hop.
· Use the opcode end-dx6 vpn-instance command to manually configure an End.DX6 SID in the locator applied to the VPN instance or public instance.
Make sure the output interface specified for the next hop in the opcode end-dx6 vpn-instance command is consistent with the output interface of that next hop in the routing table. If they are inconsistent, the device cannot use the manually configured End.DX6 SID to forward traffic.
If both methods are used for the same next hop, the manually configured End.DX6 SID takes precedence over the dynamically allocated one.
You can specify only one output interface for one next hop. To change the output interface of a next hop, first use the undo nexthop command to remove the original next hop and output interface association.
The device might be unable to dynamically allocate SIDs to BGP IPv6 routes based on the route next hops when dynamic SID resources are insufficient. If the device does not have manually configured End.DX6 SIDs, it allocates the End.DT6 SID or End.DT46 SID of the VPN instance or public instance to the routes.
Examples
# In BGP IPv6 SR next hop view, allow the system to allocate an End.DX6 SID to next hop 10::1:2 and specify Ten-GigabitEthernet 2/0/0 as the output interface of the next hop.

ipv6-address: Specifies a peer by its IPv6 address. The peer must exist.
prefix-length: Specifies a prefix length in the range of 0 to 128. To specify a subnet, you must specify both the ipv6-address and prefix-length arguments.
replace-rt: Modifies route information.
· Replaces the RD and route targets of VPNv4 or VPNv6 routes with those of the matching local VPN instance, and adds MPLS labels or SRv6 SIDs to the routes. If you do not specify this keyword, the device performs the same operations except that it does not replace the route targets.
· Replaces the L3 VXLAN ID, RD, and route targets of EVPN IP prefix advertisement routes with those of the matching local VPN instance, and adds MPLS labels or SRv6 SIDs to the routes. If you do not specify this keyword, the device performs the same operations except that it does not replace the route targets.
Usage guidelines
Use this command on a PE that connects the MPLS L3VPN and MPLS L3VPN over SRv6 networks or connects the EVPN L3VPN and EVPN L3VPN over SRv6 networks.This command enables the PE to modify VPNv4, VPNv6, or EVPN route information to realize intercommunication between the MPLS and SRv6 networks.
After you execute this command on a PE, the PE performs the following operations after receiving BGP VPNv4, VPNv6, or EVPN routes from the MPLS L3VPN or EVPN L3VPN network:
1. Matches the route targets of the routes with the import route targets of local VPN instances.
2. Replaces the L3 VXLAN ID (for EVPN L3VPN), RD, and route targets of the routes with those of the matching local VPN instance. In addition, the PE adds an SRv6 SID to the routes and maps the SRv6 SID of the routes to the private label of the routes.
3. Advertises the reoriginated routes to the SRv6 network.
After you execute this command on a PE, the PE performs the following operations after receiving BGP VPNv4, VPNv6, or EVPN routes from the SRv6 network:
1. Matches the route targets of the routes with the import route targets of local VPN instances.
2. Replaces the L3 VXLAN ID (for EVPN L3VPN), RD, and route targets of the routes with those of the matching local VPN instance. In addition, the PE adds MPLS labels to the routes and maps the private label of the routes to the SRv6 SID of the routes.
3. Advertises the reoriginated routes to the MPLS L3VPN or EVPN L3VPN network.
After you execute this command on a PE, the PE advertises only reoriginated routes to the specified peer or peer group. The original routes are not advertised.
If the RD of a received BGP VPNv4, VPNv6, or EVPN route is identical to the RD of the matching local VPN instance, a PE does not modify the route or reoriginate the route. As a result, the PE does not advertise the route. As a best practice, assign unique RDs to VPN instances on different devices if you use this command.
Examples
# In BGP VPNv4 address family view, replace the RD and route targets of the BGP VPNv4 routes received from peer 1.1.1.1 and add an MPLS label or SRv6 SID to the routes.

Parameters
vsi vsi-name: Specifies a VSI by its name, a case-sensitive string of 1 to 31 characters.
mac mac-address: Specifies a host attached to a remote PE by its MAC address in H-H-H format. Do not specify a broadcast MAC address, multicast MAC address, or all-zeros MAC address.
end-op endop: Specifies an End.OP SID to be added to MPLS echo requests. The End.OP SID is used to locate the destination node. If you do not specify an End.OP SID, the device does not add an End.OP SID to MPLS echo requests.
-a source-ipv6: Specifies the source IPv6 address of MPLS echo requests. If you do not specify a source IPv6 address, the IPv6 address of the traffic output interface is used as the source IPv6 address of MPLS echo requests.
-c count: Specifies the number of MPLS echo requests to be sent. The value range for the count argument is 1 to 4294967295, and the default value is 5.
-h hop-limit: Specifies the maximum number of hops allowed for an MPLS echo request. The value range for the hop-limit argument is 1 to 255, and the default value is 255.
-m interval: Specifies the interval at which an MPLS echo request is sent, in milliseconds. The value range for the interval argument is 1 to 10000, and the default value is 2000.
-r reply-mode: Specifies the reply mode used by the receiver (the remote PE) to reply to MPLS echo requests. The value for the reply-mode argument can be 2 or 4, and the default value is 2. If the mode is 2, the receiver searches the IP forwarding table for the destination IP address to forward MPLS echo replies. If the mode is 4, the receiver searches the IPv6 routing table for the source IPv6 address of the echo requests, encapsulates an SRH to the replies, and forwards them.
-s packet-size: Specifies the length of MPLS echo requests, in bytes. The value range for the packet-size argument is 80 to 1200, and the default value is 100. The specified packet length does not include the IPv6 header and UDP header length.
-t time-out: Specifies the timeout time of MPLS echo replies, in milliseconds. The value range for the time-out argument is 0 to 65535, and the default value is 2000. If the local PE does not receive an MPLS echo reply within the timeout time after sending an MPLS echo request, it determines that the MPLS echo reply times out.
-tc tc: Specifies the traffic class value in MPLS echo requests. The value range for the tc argument is 0 to 255 and the default value is 0.
Usage guidelines
In an EVPN VPLS over SRv6 network, a PE transmits data packets to a remote PE over an SRv6 PW. Use this command to test the connectivity of the SRv6 PW from the local PE to the remote PE when packet loss or traffic interruption occurs between the PEs.

Parameters
xconnect-group group-name: Specifies a cross-connect group by its name, a case-sensitive string of 1 to 31 characters. The string cannot contain a hyphen (-).
local-service-id: Specifies a local service ID in the range of 1 to 16777215.
remote-service-id: Specifies a remote service ID in the range of 1 to 16777215.
-a source-ipv6: Specifies the source IPv6 address of MPLS echo requests. If you do not specify a source IPv6 address, the IPv6 address of the traffic output interface is used as the source IPv6 address of MPLS echo requests.
-c count: Specifies the number of MPLS echo requests to be sent. The value range for the count argument is 1 to 4294967295, and the default value is 5.
-h hop-limit: Specifies the maximum number of hops allowed for an MPLS echo request. The value range for the hop-limit argument is 1 to 255 and the default value is 255.
-m interval: Specifies the interval at which an MPLS echo request is sent. The value range for the interval argument is 1 to 10000 milliseconds and the default value is 2000 milliseconds.
-r reply-mode: Specifies the reply mode used by the receiver (the remote PE) to reply to MPLS echo requests. The value for the reply-mode argument can be 2 or 4, and the default value is 2. If the mode is 2, the receiver searches the IP forwarding table for the destination IP address to forward MPLS echo replies. If the mode is 4, the receiver searches the IPv6 routing table for the source IPv6 address of the echo requests, encapsulates an SRH to the replies, and forwards them.
-s packet-size: Specifies the length of MPLS echo requests, in bytes. The value range for the packet-size argument is 80 to 1200, and the default value is 100. The specified packet length does not include the IPv6 header and UDP header length.
-t time-out: Specifies the timeout time of MPLS echo replies, in milliseconds. The value range for the time-out argument is 0 to 65535, and the default value is 2000. If the local PE does not receive an MPLS echo reply within the timeout time after sending an MPLS echo request, it determines that the MPLS echo reply times out.
-tc tc: Specifies the traffic class value in MPLS echo requests. The value range for the tc argument is 0 to 255 and the default value is 0.

segment-routing ipv6
Use segment-routing ipv6 to specify a route recursion mode.
Use undo segment-routing ipv6 to restore the default.
Syntax
In EVPN instance view:
segment-routing ipv6 { best-effort | traffic-engineering | traffic-engineering best-effort }
undo segment-routing ipv6
In cross-connect group EVPN instance view or VSI EVPN instance view:
segment-routing ipv6 { best-effort | traffic-engineering [ track-bfd ] | traffic-engineering [ track-bfd ] best-effort }

Default
The device searches the IPv6 routing table based on the next hop of a matching EVPN route to forward traffic.
Views

Predefined user roles
network-admin
Parameters
best-effort: Specifies the SRv6 BE mode.
traffic-engineering: Specifies the SRv6 TE mode.
traffic-engineering best-effort: Specifies the SRv6 TE and SRv6 BE hybrid mode.
track-bfd: Associates the SRv6 TE policy that contains paths between two PEs with the static BFD session specified for testing the IP connectivity between the PEs in SRv6 TE mode. For this purpose, you must specify this keyword and create a static BFD session to test the IP connectivity between the two PEs. If the static BFD session goes down, the state of the SRv6 TE policy also changes to down. This mechanism avoids traffic forwarding failure caused by path disconnectivity.
Usage guidelines
Use this command in an EVPN VPWS over SRv6 or EVPN VPLS over SRv6 network.
After the PE receives a customer packet destined for an End.DX2, End.DT2M, or End.DT2U SID, it forwards the packet according to the route recursion mode.
· SRv6 BE mode—This mode is also called SID-based forwarding mode. In this mode, the PE first encapsulates the End.DX2, End.DT2M, or End.DT2U SID into the packet. Then, the PE searches the IPv6 routing table based on the SID encapsulated in the packet to forward the packet.
· SRv6 TE mode—This mode is also called next hop-based forwarding mode. In this mode, when the PE forwards the packet, it first searches the tunnel policies for a matching SRv6 TE policy based on the next hop of a matching route. Then, the PE adds an SRH to the packet. The SRH includes the End.DX2, End.DT2M, or End.DT2U SID and the SID list of the SRv6 TE policy. Finally, the PE forwards the encapsulated packet through the SRv6 TE policy.
· SRv6 TE and SRv6 BE hybrid mode—In this mode, the PE preferentially uses the SRv6 TE mode to forward the packet. If no SRv6 TE policy is available for the packet, the PE forwards the packet in SRv6 BE mode.

Parameters
locator-name: Specifies a locator by its name, a case-sensitive string of 1 to 31 characters. The specified locator must exist.
evpn: Adds the SID attribute to private network routes when the routes are converted to EVPN routes. If you do not specify this keyword, the command adds the SID attribute to private network routes when the routes are converted to BGP VPNv4 or VPNv6 routes.
auto-sid-disable: Disables automatic SRv6 SID allocation. If you do not specify this keyword, the device allows dynamically allocated SRv6 SIDs. If static SRv6 SIDs are configured when automatic SRv6 SID allocation is enabled, the static SRv6 SIDs take precedence. If no static SRv6 SIDs are configured when automatic SRv6 SID allocation is enabled, the system dynamically allocates SRv6 SIDs.
Usage guidelines
Use this command to enable a BGP family to use BGP routes to advertise SRv6 SIDs in the specified locator.
If you execute this command multiple times for the same address family, the most recent configuration takes effect.

Parameters
best-effort: Switches to the SRv6 BE route recursion mode when the matching SRv6 TE policy tunnel fails for L3VPN traffic. If you do not specify this keyword, the PE looks up the routing table based on the destination IP address to forward L3VPN traffic when the matching SRv6 TE policy tunnel fails.
evpn: Recurses the private network routes based on the SID attribute in EVPN routes. If you do not specify this keyword, the device recurses the private network routes based on the SID attribute in BGP VPNv4 or VPNv6 routes.
Usage guidelines
This command is applicable to the MPLS L3VPN over SRv6 and EVPN L3VPN over SRv6 networks. This command enables PEs to recurse routes to SRv6 TE policy tunnels and use the tunnels to forward L3VPN traffic between the PEs.
To improve high availability for L3VPN packet forwarding, specify the best-effort keyword. A PE forwards an L3VPN packet as follows:
1. The PE forwards the packet through the matching SRv6 TE policy tunnel.
2. If the matching SRv6 TE policy tunnel fails, the PE forwards the packet in SRv6 BE mode.
3. If the packet forwarding still fails in SRv6 BE mode, the PE forwards the packet by looking up the routing table based on the destination IP address of the packet.
4. If the packet forwarding still fails, the PE drops the packet.
Use this command in different address family views according to your network scenario.
· In the private network IPv4 or IPv6 over SRv6 scenario, use this command in BGP-VPN IPv4 unicast address family view or BGP-VPN IPv6 unicast address family view.
· In the public network IPv4 or IPv6 over SRv6 scenario, use this command in BGP IPv4 unicast address family view or BGP IPv6 unicast address family view.
This command is mutually exclusive with the segment-routing ipv6 best-effort command.

Parameters
ethernet: Specifies the SRv6 PW data encryption type as Ethernet.
vlan: Specifies the SRv6 PW data encryption type as VLAN.
Usage guidelines
With Ethernet specified as the SRv6 PW data encryption type, the frames transmitted on the SRv6 PW cannot carry P-Tags (service delimiters added to distinguish users as required by ISPs).
· If the PE receives a packet carrying a P-Tag from the CE, it removes the P-Tag, adds an SRv6 SID, and then forwards the packet.
· If the PE receives a packet without a P-Tag from the CE, it directly adds an SRv6 SID, and then forwards the packet.
· For a packet to be sent to the CE, if the access mode is specified as VLAN with the ac interface command, the PE adds the P-Tag and then forwards the packet to the CE. If the access mode is specified as Ethernet, the PE forwards the packet to the CE without adding a P-Tag. In addition, it does not rewrite or remove any tags.
With VLAN specified as the SRv6 PW data encryption type, the frames transmitted on the SRv6 PW must carry P-Tags.
· If the PE receives a packet carrying a P-Tag from the CE, it retains the P-Tag, adds an SRv6 SID, and then forwards the packet.
· If the PE receives a packet without a P-Tag from the CE, it adds an empty P-Tag with value 1, adds an SRv6 SID, and then forwards the packet.
· For a packet to be sent to the CE, if the access mode is specified as VLAN with the ac interface command, the PE rewrites or retains the P-Tag and then forwards the packet to the CE. If the access mode is specified as Ethernet, the PE removes the P-Tag and then forwards the packet to the CE.

mac mac-address: Specifies a host attached to a remote PE by its MAC address in H-H-H format. Do not specify a broadcast MAC address, multicast MAC address, or all-zeros MAC address.
end-op endop: Specifies an End.OP SID to be added to MPLS echo requests. The End.OP SID is used to locate the destination node. If you do not specify an End.OP SID, the local PE does not add an End.OP SID to MPLS echo requests.
-a source-ipv6: Specifies the source IPv6 address of MPLS echo requests. If you do not specify a source IPv6 address, the IPv6 address of the traffic output interface is used as the source IPv6 address of MPLS echo requests.
-h hop-limit: Specifies the maximum number of hops allowed for an MPLS echo request. The value range for the hop-limit argument is 1 to 255, and the default value is 255.
-r reply-mode: Specifies the reply mode used by the receiver (the remote PE) to reply to MPLS echo requests. The value for the reply-mode argument can be 2 or 4, and the default value is 2. If the mode is 2, the receiver searches the IP forwarding table for the destination IP address to forward MPLS echo replies. If the mode is 4, the receiver searches the IPv6 routing table for the source IPv6 address of the echo requests, encapsulates an SRH to the replies, and forwards them.
-t time-out: Specifies the timeout time of MPLS echo replies, in milliseconds. The value range for the time-out argument is 0 to 65535, and the default value is 2000. If the local PE does not receive an MPLS echo reply within the timeout time after sending an MPLS echo request, it determines that the MPLS echo reply times out.
-tc tc: Specifies the traffic class value in MPLS echo replies. The value range for the tc argument is 0 to 255 and the default value is 0.
Usage guidelines
In an EVPN VPLS over SRv6 network, a PE transmits data packets to a remote PE over an SRv6 PW.
