RE: Rip authentication problem

This is usually one of two things, first you maybe have emty spaces at the
end of the key and second "order of operation"... Make sure you do the
config in the right order.
Be sure that you have made the key chains before you enter the config on to
the interface..

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?

R1:

key chain RIP
 key 1
  key-string CISCO

 ip address 192.10.1.1 255.255.255.0

Thank you,
