Parameters

destination: IP address of the peer PE.

vc-id: VC ID of the L2VPN connection, in the range of 1 to 4294967295.

control-word: Enables the control word option.

no-control-word: Disables the control word option.

ethernet: Specifies the PW encapsulation type of Ethernet. In Ethernet mode, P-Tag is not transferred on the PW. For a packet from a CE, if it contains the service delimiter, the PE removes the service delimiter and adds a PW label and a tunnel label into the packet before forwarding the packet. Otherwise, the PE adds a PW label and a tunnel label into the packet and then forwards the packet. For a packet to be sent downstream, whether the PE adds the service delimiter into the packet depends on your configuration. However, rewriting and removing of existing tags are not allowed.

vlan: Specifies the PW encapsulation type of VLAN. In VLAN mode, packets transmitted over the PW must carry a P-Tag. For a packet from a CE, if it contains the service delimiter, the PE keeps the P-TAG unchanged or changes the P-tag to the VLAN tag expected by the peer PE or to a null tag (the tag value is 0), and then adds a PW label and a tunnel label into the packet before sending the packet out. If the packet contains no service delimiter, the PE adds the VLAN tag expected by the peer PE or a null tag, and then a PW label and a tunnel label into the packet before sending the packet out. For a packet to be sent downstream, the PE rewrites, removes, or retains the service delimiter depending on your configuration.

tunnel-policy tunnel-policy-name: Specifies the tunneling policy for the VC. The tunneling policy name is a case-insensitive string of 1 to 19 characters.

Description

Use mpls l2vc to create a Martini L2VPN connection.

Use undo mpls l2vc to delete the Martini connection.

If you do not specify the tunneling policy, or if you specify the tunneling policy name but do not configure the policy, the default policy is used for the VC. The default tunneling policy selects only one tunnel (no load balancing) in this order: LSP tunnel CR-LSP tunnel. For information about configuring a tunneling policy, see MPLS Configuration Guide.

Only L2VPNs that use PPP, FR, or HDLC encapsulation support the control word option.

The PW encapsulation type can be Ethernet or VLAN. The switch allows you to specify the PW encapsulation type for only Layer 3 Ethernet interfaces and subinterfaces, and VLAN interfaces. When not specified, the PW encapsulation type depends on the interface type: it is Ethernet on Layer 3 Ethernet interfaces, and VLAN on Layer 3 Ethernet subinterfaces and VLAN interfaces.

Related commands: tunnel-policy.

Parameters

ethernet: Specifies the PW transport mode as Ethernet mode.

vlan: Specifies the PW transport mode as VLAN mode.

Description

Use trans-mode to specify the PW transport mode.

Use undo trans-mode to restore the default.

By default, the PW transport mode is VLAN.

In Ethernet mode, P-Tag is not transferred on the PW. For a packet from a CE, if it contains the service delimiter, the PE removes the service delimiter and adds a PW label and a tunnel label into the packet before forwarding the packet. Otherwise, the PE adds a PW label and a tunnel label into the packet and then forwards the packet. For a packet to be sent downstream, whether the PE adds the service delimiter into the packet depends on your configuration. However, rewriting and removing of existing tags are not allowed.

In VLAN mode, packets transmitted over the PW must carry a P-Tag. For a packet from a CE, if it contains the service delimiter, the PE keeps the P-TAG unchanged or changes the P-tag to the VLAN tag expected by the peer PE or to a null tag (the tag value is 0), and then adds a PW label and a tunnel label into the packet before sending the packet out. If the packet contains no service delimiter, the PE adds the VLAN tag expected by the peer PE or a null tag, and then a PW label and a tunnel label into the packet before sending the packet out. For a packet to be sent downstream, the PE rewrites, removes, or retains the service delimiter depending on your configuration.

Parameters

peer-ip-address: IP address of the remote peer.

pw-id pw-id: Specifies the PW ID of the Martini MPLS L2VPN connection, in the range of 1 to 4294967295.

access-mode: Specifies the access mode of the service instance as Ethernet or VLAN. The default access mode is VLAN.

vlan: Specifies the access mode of VLAN.

mtu mtu-value: Specifies the MTU in the range of 46 to 65535. The default is 1500.

pw-class class-name: Specifies a PW class by its name. class-name is a case-insensitive string of 1 to 19 characters. If you do not specify a PW class, or you specify a PW class but the PW class does not specify a tunneling policy or the specified tunneling policy is not configured, the default tunneling policy will be used. The default tunneling policy selects only one tunnel in this order: LSP tunnel, CR-LSP tunnel. For information about configuring a tunneling policy, see MPLS Configuration Guide.

Description

Use xconnect peer to create a Martini MPLS L2VPN connection for a service instance.

Use undo xconnect peer to delete the MPLS L2VPN connection of a service instance.

The access mode of a service instance can be either of the following:

· VLAN mode—The Ethernet header of a packet sent from a CE to a PE or from a PE to a CE includes a VLAN tag that is added in the header as a service delimiter for the service provider network to identify the user. The tag is called a "P-Tag".

· Ethernet mode—The Ethernet header of a packet sent from a CE to a PE or from a PE to a CE does not contain any service delimiter. If the header contains a VLAN tag, it is the internal VLAN tag of the user and means nothing to the PE. Such an internal VLAN tag of a user is called a "U-Tag".

The MTU specified by this command is advertised through LDP and used for PW negotiation.

This command is available for service instances with the ID in the range of 1 to 4094.

Related commands: pw-class.

NOTE:

The MTU specified is only used for possible parameter negotiation.

Examples

# For service instance 100, create a Martini MPLS L2VPN connection and specify the matching external VLAN tag as 100.
