MPLS L2VPN commands

ac interface

Use ac interface in cross-connect view to bind an Ethernet service instance to 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 service-instance instance-id [ access-mode { ethernet | vlan } ] [ track track-entry-number&<1-3> ]

undo ac interface interface-type interface-number service-instance instance-id

Default

No Ethernet service instance is bound to a cross-connect.

Parameters

interface-type interface-number: Specifies an interface by its type and number.

service-instance instance-id: Specifies an Ethernet service instance by its ID in the range of 1 to 4096.

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

·     ethernet: Specifies the Ethernet access mode.

·     vlan: Specifies the VLAN access mode.

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 execute this command, packets matching the Ethernet service instanceare forwarded to the bound PW or another AC.

The Ethernet service instance specified in this command must have a packet match criterion configured by the encapsulation command.

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

in-label in-label-value: Specifies an incoming label. The value range for the in-label-value argument is 16 to 1023.

out-label out-label-value: Specifies an outgoing label in the range of 16 to 1048575.

nexthop nexthop: Specifies the IP address of the next hop.

out-interface interface-type interface-number: Specifies the outgoing interface by its type and number.

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 Ethernet service instance. The PE can forward packets matching the Ethernet service instance to 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, VLAN interfaces, or Layer 3 aggregate 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.

Examples

# Create a remote CCC connection that has incoming label 100, outgoing label 200, and next hop 10.1.1.1.

<Sysname> system-view

[Sysname] xconnect-group bbb

[Sysname-xcg-bbb] connection ccc1

encapsulation

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

Use undo encapsulation to restore the default.

Syntax

encapsulation s-vid vlan-id [ c-vid vlan-id ]

encapsulation { default | tagged | untagged }

undo encapsulation

Default

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

Views

Ethernet service instance view

Predefined user roles

network-admin

Parameters

c-vid: Matches packets with the specified inner VLAN IDs.

s-vid: Matches packets with the specified outer VLAN IDs.

vlan-id: Specifies a VLAN ID in the range of 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 all 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

The match criteria of different Ethernet service instances cannot overlap on an interface.

An Ethernet service instance can contain only one match criterion. To change the match criterion, first execute the undo encapsulation command to remove the original criterion. When you remove the match criterion in an Ethernet service instance, the mapping between the service instance and the cross-connect is removed automatically.

Examples

# Configure Ethernet service instance 1 on Ten-GigabitEthernet 1/0/1 to match packets that have an outer VLAN ID of 111.

<Sysname> system-view

[Sysname] interface ten-gigabitethernet 1/0/1

Parameters

size: Specifies an MTU value. The value range is 300 to 65535.

Usage guidelines

The specified MTU applies to all PWs established in the cross-connect view or the auto-discovery cross-connect group view.

The MTU specifies the maximum packet length, including the PW label, and network layer packet.

For an LDP PW to come up, the PEs at the two ends of the PW must have the same MTU.

Examples

# Set the MTU to 1400 bytes for cross-connect ac2pw in cross-connect group vpn1.

<Sysname> system-view

[Sysname] xconnect-group vpn1

[Sysname-xcg-vpn1] connection ac2pw

Use undo peer to delete a PW for a cross-connect.

Syntax

peer ip-address pw-id pw-id [ ignore-standby-state | in-label label-value out-label label-value ] [ tunnel-policy tunnel-policy-name ] *

undo peer ip-address pw-id pw-id

Default

No PWs exist for a cross-connect.

Views

Cross-connect view

Predefined user roles

network-admin

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. This keyword is applicable only to LDP PWs.

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

out-label label-value: Specifies the outgoing label of the PW. The value range is 16 to 1048575.  

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 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.

The PW ID for a PW must be the same on the PEs at the two 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.

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.

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 an LDP PW destined to 4.4.4.4 for cross-connect pw2pw in cross-connect group vpn1 and enter cross-connect PW view. The PW ID is 200.

<Sysname> system-view

[Sysname] xconnect-group vpn1

peer signaling

Use peer signaling to enable BGP to exchange label block information with the specified peer or peer group.

Use undo peer signaling to disable BGP to exchange label block information with the specified peer or peer group.

Syntax

peer { group-name | ip-address [ mask-length ] } signaling [ non-standard ]

undo peer { group-name | ip-address [ mask-length ] } signaling

Default

BGP can exchange label block information with an L2VPN peer or peer group through RFC 4761 MP_REACH_NLRI.

Views

BGP L2VPN address family view

Predefined user roles

network-admin

Parameters

group-name: Specifies a peer group by its name, a case-sensitive string of 1 to 47 characters. The specified peer group must have been created.

ip-address: Specifies a peer by its IP address. The specified peer must have been created.

mask-length: Specifies a mask length in the range of 0 to 32. You can use the ip-address and mask-length arguments together to specify a subnet. If you specify a subnet, this command enables BGP to exchange label block information with all dynamic peers in the subnet.

non-standard: Uses draft-kompella-ppvpn-l2vpn-03 MP_REACH_NLRI to exchange label block information. If you do not specify this keyword, RFC 4761 MP_REACH_NLRI is used to exchange label block information.

Usage guidelines

L2VPN uses MP-BGP to exchange label blocks when creating a BGP PW.

To enable BGP to exchange label blocks with the specified peers through RFC 4761 MP_REACH_NLRI, you can also use the peer enable command in BGP L2VPN address family view. To disable the capability, use the undo peer signaling command.

Examples

# Enable BGP to exchange label block information with the peer 3.3.3.9 through draft-kompella-ppvpn-l2vpn-03 MP_REACH_NLRI.

policy vpn-target

Use policy vpn-target to enable route target-based filtering of incoming BGP L2VPN information.

Use undo policy vpn-target to disable route target-based filtering of incoming BGP L2VPN information.

Syntax

policy vpn-target

undo policy vpn-target

Default

Route target-based filtering of incoming BGP L2VPN information is enabled.

Views

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.

To establish a BGP PW between two MP-IBGP peers that use a route reflector, you must disable route target-based filtering of incoming BGP L2VPN information on the route reflector.

Examples

# Disable route target-based filtering of incoming BGP L2VPN information.

route-distinguisher

Use route-distinguisher to configure a route distinguisher (RD) for a BGP cross-connect group.

Use undo route-distinguisher to restore the default.

Syntax

route-distinguisher route-distinguisher

undo route-distinguisher

Default

No RD is configured for a BGP cross-connect group.

Views

Auto-discovery cross-connect group view

Predefined user roles

network-admin

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.

Examples

# Configure the RD 22:2 for BGP cross-connect group bbb.

<Sysname> system-view

[Sysname] xconnect-group bbb

[Sysname-xcg-bbb] auto-discovery bgp

[Sysname-xcg-bbb-auto] route-distinguisher 22:2

rr-filter

Use rr-filter to create a route reflector (RR) reflection policy.

Use undo rr-filter to restore the default.

Syntax

Parameters

ext-comm-list-number: Specifies an extended community list number in the range of 1 to 65535.

Usage guidelines

After this command is executed, only the L2VPN information that is permitted by the specified extended community list is reflected.

By configuring different RR reflection policies on RRs in a cluster, you can implement load balancing among the RRs.

Use site to create a local site and enter its view, or enter the view of an existing local site.

Use undo site to delete a local site.

Syntax

site site-id [ range range-value ] [ default-offset default-offset ]

undo site site-id

Default

No sites exist.

Views

Auto-discovery cross-connect group view

Predefined user roles

network-admin

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.

<Sysname> system-view

[Sysname] xconnect-group bbb

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 cross-connect 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.

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.

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 BGP cross-connect group bbb.
