Re: OSPF Weird Issue

Hey,
This is not hub and spoke , full mesh frame relay mapping and evryone can
reach evryone in the topology so I dont think so any issues with the L2
connectivity.All L2 and L3 are up and running. So no issue with DR and BDR
also
When i clear the process also, i m getting the same issue.
