Lab: Inter-AS Option A

Lab Description
This lab has two different ISP ASNs connecting to each other over a connection that has been sub-interfaced. The sub-interface has been placed into a test customers VRF. The test customers VRF is configured on each of the ASBRs. A standard IPv4 eBGP session has been created across the sub-interface to exchange the routes. This method is commonly referred to as Inter-AS MPLS Option A.
