3. Enable OSPF NSR.
non-stop-routing
By default, OSPF NSR is disabled.
This command takes effect only for the
current process. As a best practice,
enable OSPF NSR for each process if
multiple OSPF processes exist.
Configuring BFD for OSPF
BFD provides a single mechanism to quickly detect and monitor the connectivity of links between
OSPF neighbors, which improves the network convergence speed. For more information about BFD,
see
High Availability Configuration Guide .
OSPF supports the following BFD detection modes:
•
Bidirectional control detection —Requires BFD configuration to be made on both OSPF
routers on the link.
•
Single-hop echo detection —Requires BFD configuration to be made on one OSPF router on
the link.
