Weird question, but I can't find any trace of this on CCO.
EIGRP uses multicasts to send out hellos for neighbor discovery as does
other routing protocols. In certain environments where you cannot broadcast
or multicast that can be a problem. I tried programming in neighbors
manually and the hellos seems to be sent out in non broadcast mode.
The thing is that there is NO neighbor command documented for EIGRP, though
I looked. I tried this on 11.2 as well as 12.0 code so I know it works.
First, does anyone know the details about the function of the undocumented
neighbor command in EIGRP? Does it indeed use unicast rather than multicast
for hellos?
Second, if this is not the case is there a way to force unicast in EIGRP for
hellos?
Looking forward to the responses.
Joe
