As anybody know it can be tricky to configure rip authentication with md5.

I wonder if there are someone who have a good practice on this. Is there a speciale order you should config it?

Whenever I am going to config this, I end up doing it over and over again to get it to work.

This is especialy trikky when you will want to configure it against an pix.

Thanks!!!

Try to remember the line-up like
Key chain-->Key id-->Key string

Config mode-->Key chain key-name
Key chain mode-->Key id
Key chain-Keyid mode-->Key string password
Interface mode-->Key-chain key-name
Interface mode-->auth mode md5

Example:.
Config mode:

key chain mykey
key 1
key-string password

Interface Mode:
ip rip authentication key-chain mykey
ip rip authentication mode text | md5

Hope this would help a bit!

this is how I have configured it :

On router#1

key chain keyr1
key 1
key-string hello

interface ethernet 0
ip address 150.50.15.1 255.255.255.0
ip rip authentication mode md5
ip rip authentication key-chain keyr1

Onm pix#1

ip rip passive version 2 authentication md5 hello 1
ip rip default version 2 authentication md5 hello 1

On debug ip rip I will get that the authentication is wrong.. IT IS NOT. I have double checked.

But the strangest thing is that even if I remove authentication all together and reload router and pix, I still get wrong authentication.

In router #1 routing table the default route from the pix is showing, so the authentication works for that and hence is correct..

Have you ever experienced this
