5.7.2 Configuring Inter-AS Option A
In inter-AS Martini VLL OptionA, each ASBR must reserve a sub-interface for each inter-AS
VC. Therefore, this solution is only applicable to the situation that the number of inter-AS VCs
is small. Compared with L3VPN, this inter-AS L2VPN solution consumes more resources and
requires heavier configuration workload, which is not recommended.
Context
To configure inter-AS Martini VLL Option A, see 5.5.3 Creating a Martini VLL
Connection.
NOTE
l Configuring the ASBR by regarding the peer ASBR as the local CE
l You do not need to perform inter-AS related configurations on the ASBR or to configure the IP
addresses on the ASBR interfaces that directly connect ASBRs.
l If the inter-AS SVC VLL Option A needs to be configured, create the SVC for each AS. For the detailed
configuration, see 5.4.3 Creating an SVC VLL Connection.
5.7.3 Checking the Configuration
After an inter-AS Martini VLL is configured, you can view information about the local PW end
and the remote PW end.
Prerequisite

remote PW on the PE.
----End
