Parameters

ipv6 ipv6-address: Specifies the BSID value, which is an IPv6 address.

Usage guidelines

You can use this command to manually configure a BSID for an SRv6-TE policy or leave the SRv6-TE policy to obtain a BSID automatically. If an SRv6-TE policy has only color and endpoint configuration, the SRv6-TE policy will automatically request a BSID.

The manually configured BSID has a higher priority over the automatically obtained BSID.

The BSID configured by this command must be on the locator specified for SRv6-TE policies in SRv6 TE view. Otherwise, the SRv6-TE policy cannot forward packets.

If you execute this command multiple times, the most recent configuration takes effect.

Examples

# Set the BSID of SRv6-TE policy srv6policy to 1000::1.

Table 3 Reason why the route is not selected as the optimal route

Reason	Description
preferred-value	Routes with larger preferred values exist.
local-preference	Routes with larger local preference values exist.
as-path	Routes with smaller AS_PATH attribute values exist.
origin	There are routes whose origin has a higher priority. The route origins are IGP, EGP, and INCOMPLETE in descending order of priority.

BGP selects the optimal route from remote routes in this order: · Route learned from an EBGP peer. · Route learned from a confederation EBGP peer. · Route learned from a confederation IBGP peer. · Route learned from an IBGP peer.
igp-cost	Routes with smaller IGP metrics exist.
relydepth	Routes with smaller recursion depth values exist.
rfc5004	A route received from an EBGP peer is the current optimal route. BGP does not change the optimal route when it receives routes from other EBGP peers.
router-id	Routes with smaller router IDs exist. If one of the routes is advertised by a route reflector, BGP compares the ORIGINATOR_ID of the route with the router IDs of other routes. Then, BGP selects the route with the smallest ID as the optimal route.

peer-address	Routes advertised by peers with lower IP addresses exist.
received	Earlier learned routes exist.

explicit segment-list

Use explicit segment-list to specify a SID list for a candidate path.

Use undo explicit segment-list to delete a SID list of a candidate path or restore the default weight of a SID list.

Syntax

Default

No SID lists are specified for an SRv6-TE policy candidate path.

Parameters

segment-list-name: Specifies an SID list name, a case-sensitive string of 1 to 128 characters.

weight weight-value: Specifies a weight for the SID list, in the range of 1 to 4294967295. The default weight is 1.

Usage guidelines

An SRv6-TE policy uses the SID list specified for the highest-preference candidate path as a traffic forwarding subpath.

An SRv6-TE policy candidate path can have multiple SID lists. All the SID lists can be used to forward traffic for load sharing based on their weights. Assume SID lists a, b, and c are assigned weights x, y, z, respectively. The load of SID list a is x/(x+y+z) of the total traffic.

If you assign weight values for the same SID list multiple times, the most recent configuration takes effect.

Examples

# Configure SID list abc for the SRv6-TE policy candidate path with preference 20, and the set the SID list weight to 20.

forwarding statistics

Use forwarding statistics to configure traffic forwarding statistics for an SRv6-TE policy.

Use undo forwarding statistics to restore the default.

Syntax

forwarding statistics { disable | enable }

undo forwarding statistics

Default

An SRv6-TE policy uses the traffic forwarding statistics configuration in SRv6 TE view.

Parameters

disable: Disables the SRv6-TE policy forwarding statistics.

enable: Enables the SRv6-TE policy forwarding statistics.

Usage guidelines

You can configure traffic forwarding statistics for all SRv6-TE policies globally in SRv6 TE view or for a specific SRv6-TE policy in SRv6-TE policy view. The policy-specific configuration takes precedence over the global configuration. An SRv6-TE policy uses the global configuration only when it has no policy-specific configuration.

Predefined user roles

Usage guidelines

For the device to process only part of the received SRv6-TE policy routes, you can execute this command to enable filtering the routes by Router ID.

This command enables the device to check the Route Target attribute of a received SRv6-TE policy route. The device accepts the route only if the Route Target attribute contains the Router ID of the local device.

To use Router ID filtering, make sure you add Route Target attributes to SRv6-TE policy routes properly by using routing policy or other methods. Otherwise, Router ID filtering might learn or drop SRv6-TE policy routes incorrectly.

Examples

# Enable Router ID filtering.

Syntax

Predefined user roles

Parameters

best-effort: Enables the best-effort SRv6 forwarding mode. In this mode, L3VPN packets are forwarded by looking up the routing table according to the End.DT4 SID, End.DT6 SID, or End.DT46 SID of the packets in case of SRv6-TE policy failure. If you do not specify this keyword, L3VPN packets will be forwarded by looking up the routing table according to the destination IP address of the packets in case of SRv6-TE policy failure.

evpn: Enables EVPN L3VPN recursion to SRv6-TE policy tunnels. If you do not specify this keyword, the command enables MPLS L3VPN recursion to SRv6-TE policy tunnels.

Usage guidelines

This command applies to MPLS L3VPN and EVPN L3VPN networks where you want to use an SRv6-TE policy tunnel as the public tunnel to transfer the VPN traffic.

You can specify the best-effort keyword to improve packet forwarding reliability. In the SRv6 best effort mode, the device forwards L3VPN packets as follows:

1. Forwards L3VPN packets by using an SRv6-TE policy tunnel.

2. When the SRv6-TE policy tunnel fails, the device forwards L3VPN packets by looking up the routing table according to the End.DT4 SID, End.DT6 SID, or End.DT46 SID of the packets.

3. If SID-based forwarding fails, the device forwards L3VPN packets by looking up the routing table according to the destination IP address of the packets.

4. If the destination IP-based forwarding fails, the device drops the packets.

This command is mutually exclusive with the segment-routing ipv6 best-effort command.

# In BGP-VPN IPv4 unicast family view, enable L3VPN recursion to SRv6-TE policy tunnels.

sr-policy steering

Use sr-policy steering to configure the traffic steering mode for SRv6-TE policies.

Use undo sr-policy steering to restore the default.

Syntax

sr-policy steering [ disable | policy-based ]

undo sr-policy steering

Default

The device steering data packets to SRv6-TE policies based on colors of the packets.

Views

Predefined user roles

network-admin

mdc-admin

Parameters

disable: Does not forward traffic by using SRv6-TE policies.

policy-based: Steers traffic to an SRv6-TE policy based on the tunnel policy.

Usage guidelines

The following traffic steering modes are available for SRv6-TE policies:

· Based on color—The device searches for an SRv6-TE policy whose color and endpoint address match the color and nexthop address of a BGP route. If a matching SRv6-TE policy exists, the device recurse the BGP route to that SRv6-TE policy. Then, when the device receives packets that match the BGP route, it forwards the packets through the SRv6-TE policy.

· Based on tunnel policy—-On the ingress PE of an MPLS L3VPN or EVPN L3VPN network, create an SRv6-TE policy with endpoint address as an End.DT4 SID, End.DT6 SID, or End.DT46 SID. Configure a preferred tunnel or load sharing tunnel policy that uses the SRv6-TE policy. In this way, the SRv6-TE policy will be used as the public tunnel to carry the packets of a VPN instance. For more information about the tunnel policy configuration, see MPLS Configuration Guide.
