Seamless MPLS Configuration
This section describes how to configure seamless Multiprotocol Label Switching (MPLS) in various usage scenarios.
- Overview
Seamless MPLS is a bearer technique that extends MPLS techniques to access networks. Seamless MPLS establishes an E2E LSP across the access, aggregation, and core layers. All services can be encapsulated using MPLS at the access layer and transmitted along the E2E LSP across the three layers. - Seamless MPLS Precautions
- Configuring Intra-AS Seamless MPLS
In the intra-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. - Configuring Inter-AS Seamless MPLS
In the inter-AS seamless MPLS networking, the access and aggregation layers belong to one AS, and the core layer belong to another AS. An inter-AS BGP LSP is established across the three layers to implement E2E service connectivity. - Configuring Inter-AS Seamless MPLS+HVPN
In the inter-AS seamless MPLS+HVPN networking, an HVPN between each CSG and AGG is configured, and inter-AS seamless MPLS is configured for the link between each AGG and MASG. The networking integrates the seamless MPLS and HVPN advantages. - Configuring Dynamic BFD to Monitor a BGP Tunnel
BFD for BGP tunnel rapidly detects faults in E2E BGP tunnels. - Maintaining Seamless MPLS
The seamless MPLS maintenance involves checking the connectivity and reachability of seamless MPLS networks. - Configuration Examples
This section provides examples for configuring seamless MPLS networks. In each configuration example, the networking requirements, configuration notes, configuration roadmap, configuration procedures, and configuration files are provided.
