Hi All,

I just need confirmation on EIGRP Authentication process.
I read in the book for CCNP Route that:

1 - "Create the chain and give it a name with the key-chain name global command... . The name does not have to match ... ."

2 - "Create one or more key numbers using the key number command in key chain configuration mode.
The key numbers do not have to match on the neighboring routers."

During test I found that although the name of the key-chain does not have to match,
the key number will have to in my case in order to form neighbourship.

I configured three routers R1, R2, R3.

R1 and R2 had exact same configuration
key-chain AUTH
key 1
key-string Cisco

and it worked

R2 and R3 had different key-chain name and it worked with the same key number
but when changed key number to 100 neighboring failed and won't form.

Is this a bug in the book or I'm doing somehting wrong?
I'm preparing for CCNP Route and this is crucial I guess for the exam.

Regards
Darioosh
