Configuring Intra-AS Seamless MPLS

Configuring Intra-AS Seamless MPLS

In the intra-AS seamless MPLS networking, the access, aggregation, and core layers are within a single AS. A BGP LSP is established across the three layers within the AS to implement E2E service connectivity.

Pre-configuration Tasks

Before configuring intra-AS seamless MPLS, complete the following tasks:

  • Configure IGP protocols to implement connectivity at the access, aggregation, and core layers and enable MPLS LDP to implement the MPLS forwarding on a public network.

  • Configure IBGP peer relationships between each CSG and AGG, between each AGG and Core ABR, and between each Core ABR and MASG.

Configuration Procedure

To configure intra-AS seamless MPLS, perform the following operations in sequence.
