[c-nsp] eigrp and ospf on same switch

[Dan Letkeman]

Ben,

Thanks for the information.  I will try removing the default metric
commands to see if they are needed.

In what kind of scenario can redistributing both routing protocols
cause a routing loop?

Here is a crude diagram on how the system is setup:

Workstations---linux router w/ospf----cisco 3560 w/ospf &
eigrp----cisco 3560 w/eigrp---workstations

If I didn't redistribute both ways the devices on both sides could not
access each other.

Dan.
