Hi group,
I've three routers. Each is configured to do md5 authentication. I put in
key 1. Everything works fine. Then, I proceed to add a second key on R1
(hub) and R3.
R1:
ip ospf authentication message-digest
ip ospf message-digest-key 1 md5 cisco
ip ospf message-digest-key 2 md5 cisco2
R3:
ip ospf authentication message-digest
ip ospf message-digest-key 2 md5 cisco2
Now, only R1 and R3 form adjacency.
R2 display an error message:
*May 26 15:21:29.575: OSPF: Send with youngest Key 1
!
Serial0/0/0 : Mismatch Authentication Key - No message digest key 2 on
interface
It can't form adjacency with the hub.
Both R1 and R3 has the following info AFTER a reboot. I believe that all
three routers were working fine before the reboot.
sh ip os int s0/0/0 | in auth|key
Message digest authentication enabled
Youngest key id is 2
What is the proper way to do rollover?
TIA,
Larry
