All,
In using the "ip default-network" command to try and have a default
route passed into my IGRP routing domain to my OSPF domain. I don't
see the command in the config for it, what I do get is this..a static route
to an interface that doesn't exist.
The command I issued was: ip default-network 172.17.59.0 and added
this network under the IGRP process in question, what I get this in the
config is......
ip route 172.17.0.0 255.255.0.0 172.17.59.0
The weird thing is I can't get it out even after using the "no ip
default-network"
command. The only way I've been able to get it out is by doing a "wr erase"
and reloading the router.
Has anyone experienced this before....Please tell me what I'm doing wrong.
Nigel.
