Example for Configuring Inter-AS BGP VPLS Option C
Inter-AS BGP VPLS Option C applies to scenarios where each AS requires large numbers of inter-AS VPLS PWs. In inter-AS BGP VPLS Option C, PEs in different ASs directly exchange VPLS information, preventing ASBRs from being a significant factor in network expansion.
Networking Requirements
On the network shown in Figure 1, CE1 and CE2 access the backbone network through PE1 in AS100 and PE2 in AS200, respectively.
Inter-AS BGP VPLS Option C needs to be deployed for CE1 and CE2 to communicate.
Configuration Roadmap
The configuration roadmap is as follows:
Configure an IGP for each AS on the backbone network to ensure IP connectivity within the same AS.
Configure basic MPLS functions on the backbone network and establish a dynamic LSP between the PE and ASBR in the same AS. (ASBR interfaces also need to have basic MPLS functions configured.)
Establish an IBGP peer relationship between the PE and ASBR in the same AS.
Specify EBGP peers, configure routing policies, and enable label-based routing on ASBRs. Establish an MP-EBGP peer relationship between PE1 and PE2.
Configure VSIs on PEs and bind AC interfaces to these VSIs.
Data Preparation
To complete the configuration, you need the following data:
LSR IDs of the PEs and ASBRs
Name, RD, and VPN targets for each VSI
Names of the AC interfaces to be bound to VSIs
Routing policies used by ASBRs
Procedure
- Configure interface IP addresses.
