Use backup-peer to configure a backup PW for VPLS, and enter VSI LDP backup PW view or VSI static backup PW view. If the specified backup PW already exists, this command places you in VSI LDP backup PW view or VSI static backup PW view.

Use undo backup-peer to delete a backup PW for VPLS.

Syntax

VSI LDP PW view:

backup-peer ip-address [ pw-id pw-id ] [ pw-class class-name | tunnel-policy tunnel-policy-name ] *

undo backup-peer ip-address pw-id pw-id

VSI static PW view:

backup-peer ip-address [ pw-id pw-id ] in-label label-value out-label label-value [ pw-class class-name | tunnel-policy tunnel-policy-name ] *

undo backup-peer ip-address pw-id pw-id

Default

No backup PWs exist for VPLS.

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, in the range of 16 to 1023.

out-label label-value: Specifies the outgoing label for the backup PW, in the range of 16 to 1023.

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 type and control word for the backup PW. If you do not specify a PW class, the PW type of the backup PW is VLAN and the backup PW does not support 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 backup PW uses the default tunnel policy.

Usage guidelines

This command configures a backup PW for a PW to implement PW redundancy. The backup PW is used when the primary PW fails.

You must assign the backup PW a different peer LSR ID and PW ID than any existing VPLS PWs or cross-connect PWs.

A backup PW has the same hub and no-split-horizon attributes as its primary PW.

If both the default PW ID in the default-pw-id command and a PW ID in the backup-peer command are configured, the PW ID in the backup-peer command is used. If only the default PW ID is configured, the default PW ID is used. If no default PW ID is configured, you must provide a PW ID in the backup-peer command.

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 and a backup LDP PW for VSI vpn1, and specify the peer PE address and PW ID of the primary PW as 4.4.4.4 and 100, and those of the backup PW as 5.5.5.5 and 200.

Usage guidelines

The control word field is between the MPLS label stack and the Layer 2 data. It carries extra control information about the Layer 2 frame, for example, the sequence number. The control word feature has the following functions:

· Avoids fragment disorder. In multipath forwarding, fragments received might be disordered. You can configure the control word feature on the device, so the device can reorder the fragments according to the sequence number carried in the control word field.

· Identifies the original payload length for packets that include padding.

For packets transmitted on a PW to carry the control word field, you must enable the control word feature on both PEs of the PW.

Examples

# Enable control word for PW class pw100.

[Sysname] pw-class pw100

vpls-id vpls-id: Displays FEC 129 LDP PW label information for the VPLS instance specified by its ID, which is a string of 3 to 21 characters. You can specify a VPLS ID 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.

vsi vsi-name: Displays LDP PW label information for the VSI specified by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VSI, this command displays LDP PW label information for all VSIs.

verbose: Displays detailed information. If you do not specify this keyword, the command displays brief information.

Usage guidelines

LDP advertises FEC-to-PW label bindings in the following ways:

· After you specify a remote PE with the peer command, LDP advertises an FEC 128-to-PW label binding to the remote PE.

· After BGP discovers a remote PE, LDP advertises an FEC 129-to-PW label binding to the remote PE.

This command can display PW labels as follows:

· If you specify the pw-id pw-id option, this command displays PW labels for FEC 128.

· If you specify the vpls-id vpls-id option, this command displays PW labels for FEC 129.

· If you do not specify pw-id pw-id or vpls-id vpls-id, this command displays PW labels for both FEC 128 and FEC 129.

Use encapsulation to configure a packet match criterion for an Ethernet service instance.

Use undo encapsulation to remove a packet match criterion from an Ethernet service instance.

Syntax

encapsulation { default | tagged | untagged }

undo encapsulation

Default

No packet match criterion is configured for an Ethernet service instance.

Views

Predefined user roles

network-admin

mdc-admin

Parameters

s-vid vlan-id: Matches packets with a specific outer VLAN ID in the range of 1 to 4094.

only-tagged: Matches tagged packets. If the outer VLAN is not the PVID, the matching result does not differ, whether or not you specify the only-tagged keyword. If the outer VLAN is the PVID, the matching result depends on whether or not the only-tagged keyword is specified.

· To match only PVID-tagged packets, specify the only-tagged keyword.

· To match both untagged packets and PVID-tagged packets, do not specify the only-tagged keyword.

s-vid vlan-id c-vid vlan-id: Matches packets with a specific outer VLAN ID and a specific inner VLAN ID. The value range for the vlan-id argument is 1 to 4094.

default: Matches packets that do not match any other Ethernet service instances on the interface. On an interface, you can configure this criterion only in one Ethernet service instance. The Ethernet service instance matches any packets if it is the only instance on the interface.

tagged: Matches any packets that have a VLAN tag.

untagged: Matches any packets that do not have a VLAN tag.

Usage guidelines

An Ethernet service instance can contain only one match criterion. To change the match criterion, you must remove the original criterion first. When you remove the match criterion in an Ethernet service instance, the mapping between the Ethernet service instance and the VSI is removed automatically.

For information about inner and outer VLAN tags, see Layer 2—LAN Switching Configuration Guide.

Examples

# Configure Ethernet service instance 1 on Layer 2 Ethernet interface GigabitEthernet 1/0/1 to match packets that have an outer VLAN ID of 111 and an inner VLAN ID of 20.

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.

in-label label-value: Specifies the incoming label of the PW, in the range of 16 to 1023.

out-label label-value: Specifies the outgoing label of the PW, in the range of 16 to 1023.

hub: Specifies the PW as the hub link the VSI. After a VSI is enabled with the hub-spoke capability, a PW in the VSI is a spoke link by default. This keyword is not supported in the current software version.

no-split-horizon: Disables split horizon forwarding for the PW. By default, a PW must use the split horizon forwarding scheme to forward packets.

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 type and control word. If you do not specify a PW class, the PW type is VLAN and the PW does not support control word.

tunnel-policy tunnel-policy-name: Specifies a tunnel policy by its name, a case-insensitive string of 1 to 19 characters. If you do not specify a tunnel policy, the PW uses the default tunnel policy.

Usage guidelines

To create a static PW, you must specify the incoming and outgoing labels. To enter VSI static PW view of an existing static PW, you do not need to specify the incoming and outgoing labels.

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.

If both a default PW ID in the default-pw-id command and a PW ID in the peer command are configured, the PW ID in the peer command is used. If only a default PW ID is configured, the default PW ID is used. If no default PW ID is configured, you must provide a PW ID in the peer command.

Examples

# Configure an LDP PW for the VSI vpn1 and enter VSI LDP PW view: specify the peer PE address as 4.4.4.4, set the PW ID to 200, and disable split horizon forwarding for the PW.

Usage guidelines

If route target-based filtering is enabled, L2VPN accepts only the incoming BGP L2VPN information whose export route target attribute matches the local import route target attribute.

If route target-based filtering is disabled, L2VPN accepts all incoming BGP L2VPN information.

On an inter-AS VPN option B network, an ASBR-PE needs to store all BGP L2VPN information (VPLS PE and label block information discovered by BGP) and advertises the information to the remote ASBR-PE. To meet this need, execute the undo policy vpn-target command on the ASBR-PE to accept all incoming BGP L2VPN information.

For more information about an inter-AS VPN option B network, see MPLS Configuration Guide.

Predefined user roles

network-admin

Parameters

ethernet: Specifies the PW type as Ethernet.

vlan: Specifies the PW type as VLAN.

Usage guidelines

When the PW type is Ethernet, the PE encapsulates packets forwarded between the AC and PW as follows:

· Traffic from the AC to the PW cannot carry the P-tag assigned by the service provider.

¡ If traffic from the AC has the P-tag, the PE removes the P-tag, and adds a PW label and an outer tag into the packet before forwarding it.

¡ If traffic from the AC does not have the P-tag, the PE adds a PW label and an outer tag into the packet before forwarding it.

· For traffic received from the PW:

¡ If the AC access mode (configured by the xconnect vsi command) is VLAN, the PE adds the P-tag and forwards the traffic through the AC.

¡ If the AC access mode is Ethernet, the PE directly forwards the traffic through the AC. The PE cannot modify or delete the P-tag for the traffic from the PW.

When the PW type is VLAN, the PE encapsulates packets forwarded between the AC and PW as follows:

· Traffic from the AC to the PW must carry the P-tag.

¡ If traffic from the AC has the P-tag, the PE performs one of the following operations:

- Keeps the P-tag when the peer PE does not require the ingress to modify the P-tag.

- Changes the P-tag to the expected value (which can be zero) when the peer PE requires the ingress to modify the P-tag. Then, the PE adds a PW label and an outer tag into the packet before forwarding it.

¡ If traffic from the AC does not have the P-tag, the PE performs one of the following operations:

- Adds a P-tag of 0 when the peer PE does not require the ingress to modify the P-tag.

- Adds the expected P-tag (which can be zero) when the peer PE requires the ingress to modify the P-tag. Then, the PE adds a PW label and an outer tag into the packet before forwarding it.

· For traffic received from the PW:

¡ If the AC access mode (configured by the xconnect vsi command) is VLAN, the PE modifies or keeps the P-tag and forwards the traffic through the AC.

¡ If the AC access mode is Ethernet, the PE removes the P-tag and forwards the traffic through the AC.

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

VPLS uses RDs to differentiate the sites that reside in different VPNs and have the same site ID.

BGP adds the configured RD before the site ID. The RD and the site ID uniquely identify a VPN site.

The configured RD applies to both BGP neighbor auto-discovery and VPLS label block advertisement.

You cannot configure the same RD for different BGP VSIs.

To change an RD, you must remove the RD and then configure it again.

Parameters

tunnel-policy-name: Specifies a tunnel policy by its name, a case-sensitive string of 1 to 19 characters.

Usage guidelines

The PWs on the auto-discovery VSI use the specified tunnel policy to select public tunnels.

If you do not specify a tunnel policy or specify a nonexistent tunnel policy, the default tunnel policy applies. The default tunnel policy selects only one public tunnel for a PW in this order: LSP tunnel, CRLSP tunnel.

VPLS does not support load balancing among tunnels. If you specify a tunnel policy whose load balancing number is set to a value greater than 1, the setting does not take effect. The tunnel policy selects only one tunnel.

Examples

# Specify the tunnel policy policy1 for the auto-discovery VSI aaa.

Parameters

vpls-id: Specifies a VPLS ID, a string of 3 to 21 characters. You can specify a VPLS ID 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

A VPLS ID uniquely identifies a VPLS instance. Two PEs must have the same VPLS ID to establish a PW.

VPLS IDs are used in the scenario where BGP is used to find remote PEs and FEC 129 LDP is used to establish PWs to the remote PEs.

The local PE advertises a BGP update that includes the configured VPLS ID as an extended community attribute to the remote PE. The remote PE compares the received VPLS ID with its own VPLS ID. If the two VPLS IDs are identical, the two PEs use FEC 129 LDP to establish a PW. If not, the PEs do not establish a PW.

To change a VPLS ID, you must remove the VPLS ID and then configure it again.

Examples

# Configure the VPLS ID 100:1 for the VSI aaa.

<Sysname> system-view

[Sysname] vsi aaa

Parameters

vpn-target&<1-8>: Specifies a space-separated list of up to 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.

Examples

# Configure import route targets as 10:1 100:1 1000:1 and export route targets as 20:1 200:1 2000:1, for the auto-discovery VSI aaa.

Parameters

vsi-name: Specifies the name of a VSI, a case-sensitive string of 1 to 31 characters.

access-mode: Specifies the AC access mode. The default access mode is VLAN.

· ethernet: Specifies the access mode as Ethernet.

· vlan: Specifies the access mode as VLAN.

Usage guidelines

The AC access mode determines how the PE considers the VLAN tag in Ethernet frames received from the AC and 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 PE considers the VLAN tag as 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 PE considers it as a U-tag and ignores it. Ethernet frames sent to the AC do not carry the P-tag.

The Ethernet service instance specified in this command must have match criteria configured by encapsulation.

The switch does not support binding a Layer 3 interface to a VSI.

Examples

# Configure Ethernet service instance 200 on GigabitEthernet 1/0/1 to match packets with outer VLAN tag 200, and bind the Ethernet service instance to VSI vpn1.
