This section describes how to configure basic OSPF functions, including enabling OSPF on each router and specifying network segments in different areas.
This section describes how to configure a stub area that imports static routes. Such configuration can reduce the number of LSAs advertised to this area without affecting route reachability.
This section describes how to configure OSPF IP FRR with an example, including how to block FRR on certain interfaces to prevent the links connected to these interfaces from functioning as backup links and how to bind OSPF IP FRR to a BFD session.
This section describes how to configure BFD for OSPF. After BFD for OSPF is configured, BFD can fast detect link faults and report them to OSPF so that service traffic can be transmitted through the backup link.
This section provides an example for configuring OSPF multi-area adjacency, which includes configuration of enabling OSPF on each device, physical interface, and OSPF multi-area adjacency interface.
This section provides an example for configuring an OSPF sham link so that traffic between sites of the same VPN in the same OSPF area is forwarded through the OSPF intra-area route over the BGP/MPLS IP VPN backbone network.
