OSPF Issue
Hope someone can assist with an ospf problem - We have an existing ospf adj
running fine between R1+R2, we have just provisioned a second link, enabled
ospf and we see it form adjacency which lasts ~60seconds, then R1 sees R2 as
dead, and R2 Cannot see ourself in hello from R1, and then the whole thing
starts again.
With both adj. up(From R1):
Neighbor ID Pri State Dead Time Address
Interfacexxx.xxx.76.248 1 FULL/DR 00:00:00 xxx.xxx.66.62
Port-channel1.87xxx.xxx.76.248 1 FULL/DR 00:00:39 xxx.xxx.66.2
FastEthernet3/0
Then "new" link loses adj. after ~60seconds
Neighbor ID Pri State Dead Time Address
Interfacexxx.xxx.76.248 1 FULL/DR 00:00:38 xxx.xxx.66.2
FastEthernet3/0
NB - pings to/from both R1+R2 are clean(No loss/excessive latency), and both
ends(Ints) set to mtu of 1500.
