MPLS L2VPN commands
ac interface
Use ac interface in cross-connect view to bind a Layer 3 interfaceto a cross-connect and enter cross-connect AC view, or enter an existing cross-connect AC view.
Use ac interface in auto-discovery cross-connect view to bind a Layer 3 interface or an Ethernet service instance to a cross-connect.
Use undo ac interface to remove the binding.
Syntax
ac interface interface-type interface-number [ access-mode { ethernet | vlan } ]
undo ac interface interface-type interface-number
Default
No Layer 3 interface is bound to a cross-connect.

Parameters
interface-type interface-number: Specifies an interface by its type and number.
access-mode: Specifies the access mode.
· When the AC is a VLAN interface or Layer 3 subinterface, the default access mode is VLAN.
· When the AC is a non-VLAN Layer 3 interface, the default access mode is Ethernet.
ethernet: Specifies the Ethernet access mode.
vlan: Specifies the VLAN access mode.
Usage guidelines
After you execute this command, packets received from the Layer 3 interfaceare forwarded to the bound PW or another AC.
The access mode determines how the PE treats the VLAN tag in Ethernet frames received from the AC. It also determines how the PE forwards Ethernet frames to the AC.
· VLAN access mode—Ethernet frames received from the AC must carry a VLAN tag in the Ethernet header. The VLAN tag is called a P-tag assigned by the service provider. Ethernet frames sent to the AC must also carry the P-tag.
· Ethernet access mode—If Ethernet frames from the AC have a VLAN tag in the header, the VLAN tag is called a U-tag, and the PE ignores it. Ethernet frames sent to the AC do not carry the P-tag.

Parameters
ip-address: Specifies the LSR ID of the peer PE on the backup PW.
pw-id pw-id: Specifies a PW ID for the backup PW, in the range of 1 to 4294967295.
in-label label-value: Specifies the incoming label for the backup PW. The value range for this argument is 16 to 1023.
out-label label-value: Specifies the outgoing label for the backup PW, in the range of 16 to 1048575.
pw-class class-name: Specifies a PW class by its name, a case-sensitive string of 1 to 19 characters. You can specify a PW class to configure the PW data encapsulation type and control word for the backup PW. If you do not specify a PW class, the PW data encapsulation type is determined by the link type of the interface. The control word feature is not supported for PW data encapsulation types that do not require using control word.
tunnel-policy tunnel-policy-name: Specifies a tunnel policy by its name, a case-sensitive string of 1 to 19 characters. If you do not specify a tunnel policy, the default tunnel policy is used for the backup PW.
Usage guidelines
This command configures a backup PW to implement PW redundancy. The backup PW is used when the primary PW fails.
To configure a backup static PW, you must specify the in-label and out-label. To configure a backup LDP PW, you do not need to specify the in-label and out-label.
PW redundancy and multi-segment PW are mutually exclusive with each other. If you have configured two PWs by using the peer command, you cannot configure a backup PW for the PWs by using the backup-peer command, and vice versa.
A static PW must have a different incoming label than an existing static LSP or static CRLSP. If they are the same, the static PW is not available, even if you change the incoming label of the static LSP or the static CRLSP. To make the static PW available, delete the static PW, and reconfigure it with an unused incoming label.
Examples
# Configure a primary PW and a backup PW for cross-connect pw2pw in cross-connect group vpn2. The primary PW is destined to 6.6.6.6 and has a PW ID of 100. The backup PW is destined to 7.7.7.7 and has a PW ID of 200.

out-interface interface-type interface-number: Specifies the outgoing interface by its type and number.
pw-class class-name: Specifies a PW class by its name, a case-sensitive string of 1 to 19 characters. You can specify a PW class to configure the PW data encapsulation type and control word. If you do not specify a PW class, the PW data encapsulation type is determined by the interface type. The control word feature is not supported for PW data encapsulation types that do not require using control word.
Usage guidelines
A remote CCC connection is a static L2VPN connection that is manually created by specifying the incoming and outgoing labels on two PEs. A remote CCC connection does not need a public tunnel, but it requires configuring two static LSPs in opposite directions on each P device between the two PEs. CCC employs only one level of label to transfer packets. The static LSPs on the P devices transfer data only for the CCC connection.
This command must be configured on both the local and remote PEs to create a remote CCC connection. The outgoing label specified on a device must be the same as the incoming label specified on the next hop device.
After you create a remote CCC connection, you must execute the ac interface command to bind an interface. The PE can forward packets from the interfaceto the remote CCC connection.
Use the out-interface keyword to specify the outgoing interface only on a point-to-point link. On other interfaces, for example, Layer 3 Ethernet interfaces or VLAN interfaces, you must use the nexthop keyword to specify the next hop IP address.
For the PEs to forward packets over a CCC connection, make sure the two PEs have the same CCC connection settings such as the encapsulation type and control word feature.
Examples
# Create a remote CCC connection that has incoming label 100, outgoing label 200, and next hop 10.1.1.1, and uses PW class pwc1.
<Sysname> system-view
[Sysname] xconnect-group bbb

Usage guidelines
A cross-connect is a point-to-point connection.
You can perform the following operations in cross-connect view:
· Execute ac interface and peer to connect an AC to a PW, so the PE can forward packets between the AC and the PW.
· Execute ac interface twice to connect two ACs, so the PE can forward packets between the two ACs.
· Execute peer twice to connect two PWs to form a multi-segment PW.
· Execute ac interface and ccc to connect an AC to a remote CCC connection, so the PE can forward packets between the AC and the remote CCC connection.

Predefined user roles
network-admin
Usage guidelines
The control word field is between the MPLS label stack and the Layer 2 data. It carries control information for the Layer 2 frame, for example, the sequence number.
The control word feature can avoid fragment disorder. In multipath forwarding, fragments received might be disordered. You can configure the control word feature so the device reorders the fragments according to the sequence number carried in the control word field.
When the PW data encapsulation type is Ethernet or VLAN, the control word field is optional. Packets transmitted on the PW carry the control word field only when control word is enabled on both PEs.
Examples
# Enable the control word feature for PW class pw100.
<Sysname> system-view
[Sysname] pw-class pw100
[Sysname-pw-pw100] control-word enable

Parameters
ip-address: Specifies the LSR ID of the peer PE.
pw-id pw-id: Specifies a PW ID for the PW, in the range of 1 to 4294967295.
ignore-standby-state: Ignores the PW active/standby status bit received from the remote PE. If you do not specify this keyword, the local PE does not ignore the PW active/standby status bit received from the remote PE. This keyword is applicable only to LDP PWs.
in-label label-value: Specifies the incoming label of the PW. The value range for the label-value argument is 16 to 1023.
out-label label-value: Specifies the outgoing label of the PW, in the range of 16 to 1048575.
pw-class class-name: Specifies a PW class by its name, a case-sensitive string of 1 to 19 characters. You can specify a PW class to configure the PW data encapsulation type and control word. If you do not specify a PW class, the PW data encapsulation type is determined by the interface type. The control word feature is not supported for PW data encapsulation types that do not require using control word.
tunnel-policy tunnel-policy-name: Specifies a tunnel policy by its name, a case-sensitive string of 1 to 19 characters. If you do not specify a tunnel policy, the default tunnel policy is used.
Usage guidelines
A PE uses the PW Preferential Forwarding Status bit in LDP messages to advertise the local PWs' active/standby states. When the bit is set, it indicates that the local PW is in standby state. When the bit is cleared, it indicates that the local PW is in active state.
In independent mode, a PE considers the status bits received from the remote PEs when it selects the the forwarding PW among the set of redundant PWs. If you specify the ignore-standby-state keyword, the PE ignores the status bits received from the remote PEs and selects the forwarding PW using its own local rule.
In master/slave mode, a slave PE selects the forwarding PW among the set of redundant PWs based on the status bit received from the remote PEs. If you specify the ignore-standby-state keyword, the PE ignores the status bit received from the remote PEs and uses the primary PW to forward packets as long as the primary PW is up.
To create a static PW, you must specify the incoming and outgoing labels. To enter the view of an existing static PW, you do not need to specify the incoming and outgoing labels.
If you do not specify the incoming and outgoing labels when you create a new PW, LDP is used to create the PW.
The PW ID for a PW must be the same on the PEs at the ends of the PW.
On a PE, the LSR ID of the peer PE and the PW ID uniquely identify a PW. The peer LSR ID and PW ID combination of a PW must be unique among all VPLS PWs and cross-connect PWs.
PW redundancy and multi-segment PW are mutually exclusive with each other. If you have configured two PWs by using the peer command, you cannot configure a backup PW for the PWs by using the backup-peer command, and vice versa.
A static PW must have a different incoming label than an existing static LSP or static CRLSP. If they are the same, the static PW is not available, even if you change the incoming label of the static LSP or the static CRLSP. To make the static PW available, delete the static PW, and reconfigure it with an unused incoming label.

Parameters
independent: Specifies the independent PW redundancy operation mode.
master: Specifies the master/slave PW redundancy operation mode and uses the local PE as the master node.
Usage guidelines
This command is applicable only to LDP PWs.
LDP PWs support the independent and master/slave PW redundancy operation modes.
· Independent mode—The two PEs of a PW use LDP to advertise their respective PW active/standby state to each other. A PW can forward traffic only when it is up and active at both ends of the PW. In this mode, make sure both PEs of a PW use the independent PW redundancy operation mode.
· Master/slave mode—One PE of a PW operates as the master node and the other PE operates as the slave node. The master PE determines the PW active/standby state and then uses LDP to advertise the PW state to the slave PE. The slave PE uses the same PW state as the master PE based on the information received from the master PE. In this way, the master and slave PEs for the set of redundant PWs can use the same active PW to forward user packets.
A slave node does not advertise the PW active/standby state to the master node, and the master node ignores the PW active/standby state received from the slave nodes.
Examples
# In cross-connect view of cross-connect pw2pw in cross-connect group vpn1, specify the master/slave PW redundancy operation mode and use the local PE as the master node.

Default

Views

Predefined user roles
network-admin
Parameters
ethernet: Specifies the PW data encapsulation type as Ethernet.
vlan: Specifies the PW data encapsulation type as VLAN.
Usage guidelines
When the PW data encapsulation type is Ethernet, P-tag is not transferred on a PW.
· For a packet from a CE:
¡ If the packet contains a P-tag, the PE removes the P-tag, and adds a PW label and an outer tag into the packet before forwarding it.
¡ If the packet contains no P-tag, the PE directly adds a PW label and an outer tag into the packet before forwarding it.
· For a packet to a CE:
¡ If the access mode is configured as VLAN by using the ac interface command, the PE adds a P-tag into the packet before sending it to the CE.
¡ If the access mode is configured as Ethernet by using the ac interface command, the PE directly sends the packet to the CE.
You cannot rewrite or remove existing tags.
When the PW data encapsulation type is VLAN, packets transmitted over a PW must carry a P-tag.
· For a packet from a CE:
¡ If the peer PE does not require the ingress to rewrite the P-tag, the PE keeps the P-tag unchanged for the packet, and then encapsulates the packet. If the packet contains no P-tag, the PE adds a null label (the label value is 0) into the packet, and then encapsulates the packet.
¡ If the peer PE requires the ingress to rewrite the P-tag, the PE changes the P-tag to the expected VLAN tag (the tag value might be 0), and then adds a PW label and an outer tag into the packet. If the packet contains no P-tag, the PE adds a VLAN tag expected by the peer PE (the tag value might be 0), and then adds a PW label and an outer tag into the packet.
· For a packet to a CE:
¡ If the access mode is configured as VLAN by using the ac interface command, the PE rewrites or retains the P-tag before forwarding the packet.
¡ If the access mode is configured as Ethernet by using the ac interface command, the PE removes the P-tag before forwarding the packet.

Parameters
route-distinguisher: Specifies an RD, a string of 3 to 21 characters. An RD can be in one of the following formats:
· 16-bit AS number:32-bit user-defined number. For example, 101:3.
· 32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1.
· 32-bit AS number:16-bit user-defined number, where the AS number must be equal to or greater than 65536. For example, 65536:1.
Usage guidelines
MPLS L2VPN uses RDs to differentiate the sites with the same site ID but in different VPNs.
BGP adds the configured RD before the site ID. The RD and the site ID uniquely identify a VPN site.
You cannot configure the same RD for different BGP cross-connect groups.
To modify an RD, execute the undo route-distinguisher command to remove the RD, and then execute the route-distinguisher command.

Parameters
both: Enables sequencing for both incoming and outgoing packets on a PW.
Usage guidelines
During packet switching, packet disorder might occur due to load balancing or heavy forwarding load. To ensure that packets are forwarded correctly, enable packet sequencing on the ingress and egress PEs. Then, the ingress PE adds a sequence number to each packet on the PW, and the egress PE resequences the packets according to the sequence numbers.
If packet sequencing is enabled on the remote PE, not on the local PE, the local PE does not sequence the received packets with sequence numbers.

Parameters
site-id: Specifies a local site ID in the range of 0 to 256.
range range-value: Specifies the maximum number of sites in a VPN, in the range of 2 to 257. The default value is 10.
default-offset default-offset: Specifies the start site ID, 0 or 1. The default value is 0.
Usage guidelines
The range range-value and default-offset default-offset options determine the label block of the site.
· If you execute the site command with the range-value of range1, a label block with LR of range1 and LO of default-offset is assigned to the site.
· If you execute another site command with range-value of range2 (range2 is larger than range1), a second label block with LR of range2 to range1 and LO being range1 + default-offset is assigned to the site.
For example, if you execute the following commands, three label blocks LB1/0/10, LB2/10/12, and LB3/22/14 are assigned to site 1. LB1, LB2, and LB3 are automatically selected.
site 1 range 10 default-offset 0
site 1 range 22
site 1 range 36
You can create multiple local sites for a cross-connect group.
You can use the site command to increase the range value for an existing site. You cannot decrease the range value for an existing site with the site command. To decrease the range value, execute the undo site command to delete the site and then execute the site command.
Select a large range value to reduce future modifications for VPN expansion.
You cannot modify the default-offset for a site with the site command. To modify it, execute the undo site command to delete the site and then execute the site command.
Examples
# Create site 1, configure the VPN to contain a maximum of 30 sites, set the start site ID to 0 for cross-connect group bbb, and enter site view.

Predefined user roles
network-admin
Parameters
vpn-target&<1-8>: Specifies a space-separated list of a maximum of eight route targets.
A route target is a string of 3 to 21 characters in one of the following formats:
· 16-bit AS number:32-bit user-defined number. For example, 101:3.
· 32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1.
· 32-bit AS number:16-bit user-defined number, where the AS number must be equal to or greater than 65536. For example, 65536:1.
both: Uses the specified route targets as both import targets and export targets. The both keyword is used when you do not specify any of both, export-extcommunity, and import-extcommunity.
export-extcommunity: Uses the specified route targets as export targets.
import-extcommunity: Uses the specified route targets as import targets.
all: Removes all route targets.
Usage guidelines
A local PE sets the route targets as export targets in BGP update messages when it advertises L2VPN information through the update messages to a remote peer. The peer uses its import targets to match the received export targets. If a match is found, the peer accepts the L2VPN information.
You can repeat the vpn-target command to configure multiple route targets for a cross-connect group.
Examples
# Configure import route targets as 10:1 100:1 1000:1 and export route targets as 20:1 200:1 2000:1 for BGP cross-connect group bbb.
