How to stop this?
I am getting continuos notifications like EIGRP: received packet with MD5 authentication, key id = 1.
Have you enabled any debugs? if yes, disable that debug so that you don't get this message.
else, you could also try configuring these commands
no logg console
that way you send those message (infact all message) to logging buffer and no logg console would not throw any msgs on the console.
you can go through the message sent to the logs later by giving the command sh log
do this to disable any current active debug:
Router# u all
By the way, that syslog message indicates that the router is using Key 1 for authentication between EIGRP peers.
i am not running any debugs. and i dont want to block all the logs using no logg console.
I want to stop only these messages.
first thing you should do is to explain how are you configuring your devices, post the running config would be wise.
