Pierre-Alex,
Make sure you have the following command under the interface config:
ip rip authentication mode {text | md5}
Here is the link for rip as well. (watch the line wrap)

Subject: RIP Version 2 Authentication
I have 2 routers Router A and Router B. Router A and B both run RIP Version
2
I want Router A to require authentication from Router B before Router A can
accept Router B updates.
On Router A I have added the following:
***configuration mode******
key chain Tewa
key 1
key-string abcdefg
***interface mode******
ip rip authentication key-chain Teway
Putting the same configuration I did on Router A in Router B does not work.
I get the following message using debug ip rip: RIP: ignored v2 packet from
1.0.0.11 (invalid authentication. Do you know which commands I should use
for Router B?
Thank You
Pierre-Alex
