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.

The Martini VLL can implement inter-AS VLL Option A (VRF-to-VRF).


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.

To configure inter-AS Martini VLL using Option A, see Configuring the Martini 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 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.
