Hello,

How about EIGRP inside GRE tunnell?
Technically the packet wouldn't be an EIGRP (IP protocol 88) but rather GRE packet (IP protocol 47).
Of course, You need to do this on both sides.
HTH,
Cheers

Subject: EIGRP without passive interface

Include 3725 E0 interface in the EIGRP process. Do not send out any EIGRP
hello packets out the Ethernet interface.
Accomplish this without using any passive-interface command.

.... iam sorry i don`t understand how this is possible ..

in order for eigrp to sync it needs to send hello packets to it`s
neigbhor...

i can use the neighbor command ,which will unicast ....but it STILL sends
hello`s...

if i nat ...all i do is change the type of packet .....it`s still a hello
packet

again i could turn it into a stub ...but it still has to send heelo`s to
communicate with it`s neigbhor...

AFAIK ....you CANT communicate between eigrp host WITHOUT hello`s

can someone please clarify...

question was posed by my SE....

many thanks in advance

Stephen Skinner
