Joseph,
It supposedly should work but Cisco reports there is a bug and
recommends not using it. I tried to search on the bug but it gives me a
message about it not being able to be displayed. Not sure why. Maybe a
there is Cisco employee who could pull it for us to see what it is?
Look under "EIGRP frequently asked questions" on the Cisco site and you
will see a document called. "What does the neighbor statement in the
EIGRP configuration section do?"
http://www.cisco.com/warp/public/103/eigrpfaq.shtml#Q9
Basically it says don't use it because it does very bad things. Hmmmm...

Subject: EIGRP Manual Neighbor Configuration/Unicast
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
