Example for Configuring Inter-AS LDP VPLS Option C
Inter-AS LDP VPLS Option C applies to scenarios where each AS requires large numbers of inter-AS PWs. In inter-AS LDP VPLS Option C, PEs in different ASs directly exchange VPLS label block information. This solution frees ASBRs from maintaining a large amount of VPLS label block information and prevents ASBRs from becoming a bottleneck to network expansion.
Networking Requirements
On the network shown in Figure 1, CE1 and CE2 access the MPLS backbone network through PE1 in AS100 and PE2 in AS200, respectively.
Inter-AS LDP VPLS Option C needs to be deployed for CE1 and CE2 to communicate.
Configuration Roadmap
The configuration roadmap is as follows:
Configure an IGP protocol for each AS on the MPLS backbone network to ensure IP connectivity within the same AS.
Configure basic MPLS functions on the MPLS 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 a remote MPLS LDP session between PE1 and PE2.
Establish a VPLS connection between PE1 and PE2.
Configure VSIs on PEs and bind the VSIs to corresponding AC interfaces.
Data Preparation
To complete the configuration, you need the following data:
Data for configuring the IGP
MPLS LSR IDs of the PEs and ASBRs
VSI names
AC interfaces bound to VSIs
Routing policies used by ASBRs
Procedure
- Configure interface IP addresses.
