I am seeing weird behavior on OSPF between a 2811 Router, and a 4510R switch. A number of google searches on this came up empty. It appears as if OSPF is dropping with the following message on hourly intervals, sometimes one hour, sometime two hours, sometimes three hours. 005840: Feb 26 15:28:05.415 EST: %OSPF-5-ADJCHG: Process 300, Nbr 192.168.208.1 on Vlan208 from FULL to DOWN, Neighbor Down: Dead timer expired
This message came from the 4510R note, the OSPF config is on the SVI interface, not on the physical interface. The config for each side is as follows: 4510R interface Vlan208 description Management Interface ip address 192.168.209.254 255.255.254.0 no ip redirects no ip unreachables no ip proxy-arp ip ospf authentication message-digest ip ospf message-digest-key 1 md5 7 <hidden> ip ospf network point-to-point ip ospf resync-timeout 12 ip ospf dead-interval minimal hello-multiplier 4 ip ospf retransmit-interval 1 end 2811 interface FastEthernet0/1 ip address 192.168.208.1 255.255.254.0 no ip redirects no ip unreachables no ip proxy-arp ip ospf authentication message-digest ip ospf message-digest-key 1 md5 7 <hidden> ip ospf network point-to-point ip ospf resync-timeout 12 ip ospf dead-interval minimal hello-multiplier 4 ip ospf retransmit-interval 1 duplex auto speed auto end I've checked the MTU's, and they look consistent. Anything obvious I'm overlooking? This is at a remote site, and I've thought about having them swap the cable, but it would seem odd that a cable would so consistely fail at hourly intervals. Any ideas?
