Configuring Inter-AS BGP AD VPLS Option A

In inter-AS BGP AD VPLS Option A, an ASBR must reserve an interface as an AC interface for each inter-AS PW. Inter-AS BGP AD VPLS Option A applies to scenarios where few inter-AS PWs are required. Compared with L3VPN, inter-AS BGP AD VPLS Option A requires more resources and configuration workload.
