7.7.2 Configuring Inter-AS Kompella VPLS Option A

In inter-AS Kompella VPLS OptionA, each ASBR must reserve a sub-interface for each inter-
AS VC. If the number of inter-AS VCs is small, this solution can be used. Compared with
L3VPN, this inter-AS L2VPN solution consumes more resources and requires heavier
configuration workload, which is not recommended.
Context
The configurations of Kompella VPLS Option A can be summarized as follows:
l
l
l
Issue 01 (2011-07-15)
Configuring the VSI on the PE connected with the CE and binding the VSI to the AC
interface
Configuring the IP address on the CE interface that accesses the PE
Establishing the tunnel between the PE and the ASBR in the same AS (Option A)
Data
To configure the VSI on the PE and the ASBR, you need the following data:
l VSI name and RD
l (Optional) Description of the VSI
l VPN target
l (Optional) Routing policy that controls sending and receiving of information
about VPLS label blocks
l (Optional) Tunnel policy
l (Optional) Permitted maximum number of label blocks saved in a VSI
CE ID of the site, number of permitted CEs that access the VPLS network, CE ID
and default CE offset
PE interfaces that bound to VSIs
AS number of the PEs
IP addresses and interfaces used to establish the IBGP peers between the PEs and the
ASBRs
Configuring the Kompella VPLS for each AS
Configuring ASBR by considering the peer ASBR as its CE
Configuring the VSIs on the PE and the ASBR respectively and binding the VSIs to the
AC interfaces (The PE provides the access service for the CE; the ASBR accesses the peer
ASBRs)
