RIP Authentication

RIP authentication

Works only with RIPv2, not RIPv1.

Two steps :

1. create key :

!

key chain CCIE

 key 0   

  key-string iwillpassthelab

!

2. apply the chain on the interface and specify either clear text or md5 :

!

interface Serial1/0.123 multipoint

 ip rip authentication mode md5

 ip rip authentication key-chain CCIE

!

Key names can be different on each routers.
