[c-nsp] Problem redistributing 0.0.0.0/0 in eigrp

[Alexandra Alvarado]

Hello,

Now I have ospf working but I want to migrate to eigrp, that's why I have
ospf configuration too.

It seems that redistribution on catalyst 3550 is ok according to the shows,
but on the router is the problem, because it is not receiving the default
route.

	From redistribution's point of view it seems to be OK. Could you
provide us an output from 'show ip eigrp topology 0.0.0.0 0.0.0.0' on 3550?

	As I understand, you're using ospf for default routing at the
moment.
Am I right?
