I got a problem regarding the OPSF convergence Our mail link goes down and OSPF converged to the Backup link and now when main link goes up OSPF is not converging to main route.
below is the partial output of sh ip ospf
Area BACKBONE(0) (Inactive)
Number of interfaces in this area is 4
Area has no authentication
SPF algorithm last executed 00:50:28.720 ago
SPF algorithm executed 63 times
Area ranges are
Number of LSA 1. Checksum Sum 0x0036D9
Number of opaque link LSA 0. Checksum Sum 0x000000
Number of DCbitless LSA 0
Number of indication LSA 0

Flood list length 0
Can any one please help me .
I think restarting the router may help but i do not want to restart the routers.
