Ok I can authenticate any OSPF area with type 1 (cleartext) or type 2 (md5 hash). I can also authenticate my virtual link ...
but lets say I have hub and spoke with 3 routers
R1 is the hub and R2 and R3 are spokes off or R1 (R2 and R3 use R1 to get to each other, so not full mesh). Lets call this area 0.
Now assume that I don't want area 0 authentication but authentication between R1 s0 and R3 s0, is there a doc somewhere on this or can anyone explain the cmds?
If it was area 0 authen, type 2, I'd do this, on all 3 routers gto ensure same key throught area 0.
R1 - int s0 - ip ospf message-digest-key 1 md5 cisco and then router ospf 1 area 0 authent message-digest.
So what do I do if I only want to authenticate between R1 s0 and R3 s0?
Next question is lets say I'm not using a virtual-link but a gre tunnel, how would I authenicate the tunnel?
Regards,
John
