Hello,
We have one downstream location connected on NSSA. OSPF neighborship between ABR and downstream router is getting flucutated. In "sh log" in ABR, i'm seeing the reason being "too many retransmissions"...
%OSPF-5-ADJCHG: Process 10, Nbr x.x.x.x on Serial1/0 from FULL to DOWN, Neighbor Down: Too many retransmissions
%OSPF-5-ADJCHG: Process 10, Nbr x.x.x.x on Serial1/3 from FULL to DOWN, Neighbor Down: Too many retransmissions
%OSPF-5-ADJCHG: Process 10, Nbr x.x.x.x on Serial1/6 from FULL to DOWN, Neighbor Down: Too many retransmissions
%OSPF-5-ADJCHG: Process 10, Nbr x.x.x.x on Serial1/3 from DOWN to DOWN, Neighbor Down: Ignore timer expired
%OSPF-5-ADJCHG: Process 10, Nbr x.x.x.x on Serial1/6 from DOWN to DOWN, Neighbor Down: Ignore timer expired
What could be the reason? Can anyone advise some work around for this ??
