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.
When the access, aggregation, and core layers belong to the same AS, intra-AS seamless MPLS can be configured to implement the service connectivity between NodeBs and an MME or SGW.
When the access and aggregation layers belong to one AS, and the core layer belongs to another AS, inter-AS seamless MPLS can be configured to implement the service connectivity between a NodeB and an MME or SGW.
In the inter-AS seamless MPLS+HVPN networking, an HVPN connection between a CSG and AGG is established, and an inter-AS seamless MPLS LSP between an AGG and MASG is established. The inter-AS seamless MPLS+HVPN networking obtains the collective advantages of the inter-AS seamless MPLS network and HVPN.
This section provides an example for configuring dynamic BFD to monitor a BGP tunnel. The configuration involves configuring a BGP tunnel and configuring dynamic BFD for BGP tunnel.
