EIGRP authentication using MD5

I need to implement EIGRP authentication between routers and I have a document called "Configuring EIGRP" which has one page called 'Route Authentication Example'.

Is there a more thorough document describing this, one that explains all the different parameters?

In the one I have it just gives the router config examle with no explaination of the 'accept-lifetime', 'send-lifetime' statements. When I use this config in a lab, routing breaks and I have no way to know why. I need to know if I even need the 'accept-lifetime' or 'send-lifetime' statements, if they are optional, what they mean, etc.

Here is the example given that offers no explaination as to why the time and date were given:

Key chain holly

key-string 0987654321

accept-lifetime 04:00:00 Dec 4 1996 indinite

send-lifetime 04:00:00 Dec 4 1996 04:48:00 Dec 4 1996

Thanks.

Re: EIGRP authentication using MD5

HI Friend,

These are optional commands first of all

accept-lifetime ---> Optionally specify the time period during which the key can be received.

send-lifetime ---> Optionally specify the time period during which the key can be sent
