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 the label-value argument is 16 to 1023.

out-label label-value: Specifies the outgoing label for the backup PW. The value range is 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 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-insensitive 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.

When you add a static PW, you must make sure that static PW uses a different incoming label than an existing static LSP or static CRLSP. If the incoming label is duplicated, you cannot make the static PW take effect by changing the incoming label of the static LSP or CRLSP. Instead, you must delete the static PW and then reconfigure the static PW 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.

Packets transmitted on a PW to carry the control word field only when control word is enabled on both PEs.

Examples

# Enable control word for PW class pw100.

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.

If the PW MTUs of the two PEs of a PW are different, the MTU specified on the local device takes effect.

Examples

# In VSI LDP signaling view, disable PW MTU negotiation.

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.

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. The value range is 16 to 1048575.

hub: Specifies the PW as the hub link in the VSI. By default, a PW in the VSI enabled with the hub-spoke capability is a spoke link.

ignore-standby-state: Ignores the PW active/standby status bit received from the remote PE. This keyword is applicable only to LDP PWs.

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 data encapsulation type and control word. If you do not specify a PW class, the PW data encapsulation 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

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 master/slave mode of PW redundancy, the slave PE selects the forwarding PW among the set of redundant PWs based on the status bit received from the master PE. If you specify the ignore-standby-state keyword, the PE ignores the status bit received from the master PE 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 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 the 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 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 peer command.

Views

Predefined user roles

network-admin

Parameters

master: Uses the master/slave PW redundancy mode and configures the local PE as the master node.

Usage guidelines

This command is applicable only to LDP PWs.

For LDP PWs, PEs use LDP to negotiate the active/standby states of the PWs. In master/slave mode, one endpoint PE of a PW operates as the master node and the other endpoint PE operates as the slave node. The master PE determines the active/standby state of the PW and 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 traffic.

The slave PE does not need to send the PW states to the master PE and the master PE ignores the PW states sent by the slave PE.

Do not execute this command on the local PE if the remote PE does not support the master/slave PW redundancy mode.

Examples

# Use the master/slave PW redundancy mode and configure the local PE as the master node.

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, 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 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 data encapsulation 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 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.

To ensure successful negotiation of the encapsulation type during PW establishment, configure the same data encapsulation type on all devices in the same VPLS instance.

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 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.

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 modify an RD, execute the undo route-distinguisher command to remove the RD and then execute the route-distinguisher command.

vpls-id

Use vpls-id to set the VPLS ID for a VSI.

Use undo vpls-id to restore the default.

Syntax

vpls-id vpls-id

undo vpls-id

Default

Predefined user roles

network-admin

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 scenarios where BGP is used to find remote PEs and where 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, execute the undo vpls-id command to remove the VPLS ID and then execute the vpls-id command.

Examples

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

vpn-target

Use vpn-target to configure route targets for an auto-discovery VSI.

Use undo vpn-target to remove route targets for an auto-discovery VSI.

Syntax

vpn-target vpn-target&<1-8> [ both | export-extcommunity | import-extcommunity ]

undo vpn-target { vpn-target&<1-8> | all } [ both | export-extcommunity | import-extcommunity ]

Default

No route targets are configured for an auto-discovery VSI.

Views

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.

If you repeat this command, all the configured route targets take effect.

Examples

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

vsi

Use vsi to create a VSI and enter its view, or enter the view of an existing VSI.

Use undo vsi to delete a VSI.

Syntax

vsi vsi-name [ hub-spoke ]

undo vsi vsi-name

Default

No VSIs exist.

Views

Predefined user roles

network-admin

Parameters

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

hub-spoke: Enables the hub-spoke capability for the VSI. If you do not specify this keyword, the VSI does not have the hub-spoke capability.

Usage guidelines

You can create multiple PWs for a VSI manually, or by using LDP or BGP.

Hub-spoke is a VPLS networking model that includes one hub site and multiple spoke sites. The spoke sites communicate with one another through the hub site.

For a hub-spoke network, you must enable the hub-spoke capability for the VSI. In the VSI with hub-spoke capability, the link (AC or PW) towards the hub site is the hub link and other links towards the branch sites are spoke links. By default, all links in the VSI are spoke links. You must specify an AC or a PW as the hub link in the VSI when you configure the xconnect vsi command or the peer command.

Examples

# Create a VSI named vpls1 and enter VSI view.

<Sysname> system-view

[Sysname] vsi vpls1

[Sysname-vsi-vpls1]

xconnect vsi

Use xconnect vsi to bind a Layer 3 interface to a VSI.

Use undo xconnect vsi to restore the default.

Syntax

xconnect vsi vsi-name [ hub ] * [ track track-entry-number&<1-3> ]

undo xconnect vsi

Default

An interface is not bound to any VSI.

Parameters

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

hub: Specifies the AC as the hub link in the VSI. By default, an AC bound to a VSI enabled with hub-spoke capability is a spoke link in the VSI.

track track-entry-number&<1-3>: Specifies a space-separated list of up to three track entry numbers in the range of 1 to 1024. The AC is up only if a minimum of one associated track entry is in positive state.

Usage guidelines

After you bind a Layer 3 interface to a VSI, packets received from the interface are forwarded according to the MAC address table of the VSI.

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.

To specify the AC as the hub link by using this command, you must first enable the hub-spoke capability for the specified VSI. By default, an AC is a spoke link in a VSI enabled with the hub-spoke capability.

Examples

# Bind GigabitEthernet 1/0 to VSI vpn1, and associate the interface with track entries 1, 2, and 3.

<Sysname> system-view

[Sysname] vsi vpn1 hub-spoke

[Sysname-vsi-vpn1] quit
