EIGRP Authentication

[nawas]

I need to configure EIGRP route autentication similar to OSPF authentication. I couldn't find enough docs on CCO but there's one docs shows that I need to configure two keys on one router, can someone tell why we need two keys and if I really need to use "accept lifetime' or "send lifetime commands"

or if someone has a sampe config.

Thanks.

Hi nawas

Each key used in EIGRP has its own key identifier , which is stored locally. The combination of the key identifier and the interface associated with the message uniquely identifies the authentication algorithm and MD5 authentication key in use.

You can check out the following link for more details, there is a configuration example provided at the end of the page as well for reference
