Configuring BFD for OSPF
Applicable Environment
A link fault or a topology change causes devices to recalculate routes. Therefore, the convergence of routing protocols must be speed up to improve the network performance.
Link faults are inevitable. Therefore, a feasible solution is required to fast detect faults and notify routing protocols of the faults immediately. If BFD is associated with routing protocols, once a link fault occurs, BFD can speed up the convergence of routing protocols.
