Configuring Inter-AS VLL

Configuring Inter-AS VLL

If VLLs need to be set up over an MPLS backbone that spans multiple ASs, the inter-AS VLL must be configured.

Context

The configuration of inter-AS 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 and SVC 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 as the CE devices of each other.

NOTE:

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 ] 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.
