l Configuring the VSI on the PE connected with the CE and binding the VSI to the AC
interface
l Configuring the IP address on the CE interface that accesses the PE
l Establishing the tunnel between the PE and the ASBR in the same AS (Option A)
Data Preparation
To configure the Kompella VPLS, you need the following data.
No. Data
1 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
2
CE ID of the site, number of permitted CEs that access the VPLS network, CE ID
and default CE offset
3 PE interfaces that bound to VSIs
4 AS number of the PEs
5 IP addresses and interfaces used to establish the IBGP peers between the PEs and the
ASBRs
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 Configuring the Kompella VPLS for each AS
l Configuring ASBR by considering the peer ASBR as its CE
l 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)
