Sounds very much like a bug.... Try newer code.

Subject: Eigrp is misbehaving in a ver weird way

Hi ya'll,

Check this out.

Config for Router 4

int lo0
ip addr 198.168.4.4 255.255.255.0

int s0
ip addr 172.16.234.4 255.255.255.0

router eigrp 1
no autosummary
net 198.168.4.0
net 172.16.0.0

Here's the weird thing!!!

On this router, a show ip eigrp interfaces only shows int s0, not lo0. There
are several other routers where lo0's ip addr = 198.168.X.X where X = the
router's number.

On other routers, a similiar config results in lo0 sometimes showing up in the
output of the above show command but not always. Why?

I've tried shutting lo0 and then no shutting the interface. In those routers
where lo0 shows up in the show ip ei int, the lo0 interface is advertised as
it should be but the int isn't being advertised when it's not in the output of
sh ip ei int.

So, why isn't eigrp always picking up the lo0 interface? And, what should I
do about it?

Thanks in advance. Jim
