Greetings All,
To "...prevent unnecessary hello packets?"
The way that is worded it sounds as if this has to occur on the device sending the "...unnecessary hello packets?
Therefore you could re-address the device(s)/segment(s),
~or~
Use the passive-interface command
(will not send/rec on the passive interface, but will include this interface in updates sent on other EIGRP-enabled interfaces)
~or~
Just not run EIGRP on those interfaces
(another routing protocol perhaps?)
As far as avoiding the messages w/o EIGRP AS reconfiguration on the originator or receiver:
"no eigrp log-neighbor-warnings" on the receiving device
(Cisco officially "does not recommend doing this")
~or ~
Use a (MAC) ACL to filter in between...
Not as much of a one-liner, but may be do-able depending on what is in between the devices!
There are distribute-lists mentioned in this context throughout some docs, posts, and such; However those will not resolve this issue, as they do not impact the message of topic.
HTH,
~M

Thanks in advence for your help!
