[c-nsp] basic question about authentication with EIGRP

[Dd]

Hi,

I would like to know how can i make an authentication with twice md5 key on
eigrp, one for sending routing updates and the second for received routing
updates.
see the following sequences :

r0#sh key chain
Key-chain r0:
    key 1 -- text "send"
        accept lifetime (00:00:00 UTC Jan 1 2009) - (01:00:00 UTC Jan 1
2009)
        send lifetime (00:00:00 UTC Jan 1 2009) - (infinite) [valid now]
    key 2 -- text "receive"
        accept lifetime (00:00:00 UTC Jan 1 2009) - (infinite) [valid now]
        send lifetime (00:00:00 UTC Jan 1 2009) - (01:00:00 UTC Jan 1 2009)

I'd like to use key 1 for sending routing update but the eigrp neighboring
relation doesn't work. The key 1 is expired about accept receiving update,
how i can make for eigrp use the second, to authenticate this part.
it is possible to use twice key for eigrp authentication ?
My way is may be the wrong way, help me to solved this issue.

Thanks,

Dd.
