Need Assistance .... OSPF Too Many retransmits.... MTU not the cause
I'm trying to get OSPF running on a firepower device connected to a router.
The OSPF adjacency looks like it was created, but no routes are traded and I keep getting the following error:
*Sep 14 18:12:03.795: %OSPF-5-ADJCHG: Process 1, Nbr 0.0.0.0 on GigabitEthernet0/1/0 from DOWN to DOWN, Neighbor Down: Ignore timer expired
*Sep 14 18:14:07.676: %OSPF-5-ADJCHG: Process 1, Nbr 1.1.1.1 on GigabitEthernet0/1/0 from EXSTART to DOWN, Neighbor Down: Too many retransmissions
I have looked at a few guides and community posts on this exact issue but none of their fixes seem to work for me.
The main issue that these posts talk about is MTU issues.
Ive checked, changed, disabled, reenabled, and recreated everything on both sides
MTUs match, Router-IDs configured, sh ip ospf neighbors shows each other, but still no routes and error continues.
Here is the "debug ospf adj":
*Sep 14 18:12:03.795: OSPF-1 ADJ Gi0/1/0: 0.0.0.0 address 10.11.200.1 is dead
