Mmmm,
beside the usual remove and re-add the configuration and be careful about white spaces...
can you try adding "passive-interface e0/0" and "passive-interface f0/0" respectively?
Since you are using neighbor statements, the router is currently generating unicast and multicast advertisements out of e0/0, not sure if that may play a role here.
Not sure though...I'll lab it out as well.

Subject: Rip authentication problem
Hi,
i have a strange problem, that's driving me nuts. I configured RIP
authentication between
two routers. And i have checked the configuration many times, i can see
no error on this.
Checked whitespace in the passwords. Both routers are restarted also.
"debug ip rip" tells me still:
R1 (c2600-ik9o3s3-mz.123-10a.bin) says:
*Mar 1 00:33:25.651: RIP: ignored v2 packet from 192.10.1.6 (invalid
authentication)
*Mar 1 00:33:25.651: RIP: ignored v2 packet from 192.10.1.6 (invalid
authentication)
R6 (c2600-ik9o3s3-mz.123-10a.bin): says:
*Mar 1 00:06:27.779: RIP: received packet with MD5 authentication
*Mar 1 00:06:27.779: RIP: ignored v2 packet from 192.10.1.1 (invalid
authentication)
*Mar 1 00:06:27.779: RIP: received packet with MD5 authentication
*Mar 1 00:06:27.779: RIP: ignored v2 packet from 192.10.1.1 (invalid
authentication)
and i can't see routes are installed.
Could someone give me a hint, on how to debug this in a better way?
Seems line R6 is
even not sending md5 authentication. Is it an IOS bug?
