Configuring Inter-AS VLL

Context

The configuration of an inter-AS VLL varies with the VLL implementation mode.

The CCC mode uses a single label. Therefore, the inter-AS VLL can be set up when static LSPs are set up between ASBRs.
The Martini, SVC, and Kompella modes can implement inter-AS VLL Option A (VRF-to-VRF).

To configure inter-AS Option A, you must specify an interface (a sub-interface, a physical interface, or a bundled logical interface) for each inter-AS VC on ASBRs.

Procedure

To implement inter-AS Option A, complete basic VLL configurations in each AS and configure the ASBR-PE devices to be recognized as the CE devices by each other.

To configure an inter-AS CCC VLL, see Configuring a CCC VLL.
To configure an inter-AS Martini VLL using Option A, see Configuring a Martini VLL.
To configure an inter-AS SVC VLL using Option A, create an SVC for each AS. For the detailed configuration, see Configuring an SVC VLL.
To configure an inter-AS Kompella VLL using Option A, see Configuring a Kompella VLL.

You do not need to perform any additional configuration for inter-AS implementation on ASBRs and do not need to configure IP addresses for the directly connected interfaces between ASBRs.

Verifying the Configuration

Run the display vll ccc [ ccc-name | type { local | remote } ] command to check information about a CCC VLL.
Run the display l2vpn ccc-interface vc-type ccc [ down | up ] command to check information about interfaces used by the CCC VLL.
Run the display mpls l2vc [ vc-id | interface interface-type interface-number ] command to check PW information about the local end of a Martini VLL.
Run the display mpls l2vc remote-info [ vc-id ] command on the PE device to check PW information about the remote end of the Martini VLL.
Run the display mpls static-l2vc [ interface interface-type interface-number ] command to check information about an SVC VLL.
Run the display l2vpn ccc-interface vc-type static-vc [ down | up ] command to view information about VC interfaces in the Up/Down state on the SVC VLL.
Run the display bgp l2vpn { all | group [ group-name ] | peer [ [ peer-ip-address ] verbose ] | route-distinguisher route-distinguisher [ ce-id ce-id [ label-offset label-offset ] ] } command to check BGP routing information of a Kompella VLL.
Run the display mpls l2vpn connection [ vpn-name [ remote-ce ce-id | down | up | verbose ] | summary | interface interface-type interface-number ] command to check information about the Kompella VLL.
Run the display mpls l2vpn [ l2vpn-name [ local-ce | remote-ce ] ] command to check L2VPN information about the Kompella VLL on the PE device.
