Configuration Examples for OSPF
This section provides several OSPF configuration examples.
- Example for Configuring Basic OSPF Functions
This section describes how to configure basic OSPF functions, including enabling OSPF on each router and specifying network segments in different areas. - Example for Configuring OSPF Virtual Links
This section describes how to configure virtual links to connect a non-backbone area to the backbone area. - Example for Configuring an OSPF Stub Area
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. - Example for Configuring an OSPF NSSA
This section describes how to configure an OSPF not-so-stubby area (NSSA). - Example for Configuring OSPF DR Election
This section describes how to set the DR priority on an interface for DR election on a broadcast network. - Example for Configuring OSPF Load Balancing
This section describes how to configure OSPF load balancing, including enabling load balancing and setting priorities for equal-cost routes. - Example for Configuring OSPF Fast Convergence
This section describes how to configure OSPF fast convergence by adjusting the timer parameter and configuring BFD. - Example for Configuring OSPF Local MT
This section provides an example for configuring OSPF local multicast topology (MT). - Example for Configuring OSPF IP FRR
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. - Example for Configuring BFD for OSPF
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. - Example for Configuring OSPF-BGP Synchronization
This section describes how to configure OSPF-BGP synchronization to minimize the impact of device restart on BGP services on the network. - Example for Configuring OSPF Multi-Area Adjacency
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. - Example for Configuring an OSPF Sham Link
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.
