OSPF and EIGRP are routing protocols (layer 3) and don't have anything to do
with bridging (layer 2). You can either route or bridge a specific protocol
on the same interface. If for instance you want to bridge IPX on a
particular interface, then you would not assign that interface an IPX
address. Hence, no routing protocols would be enabled on that particular
interface. Bridging in essence is like extending your LAN so you don't need
routing to get from one side of the bridge to another.
You can, however, bridge a protocol on one interface and route it out
another interface by confgiguring IRB (Intergrated Rotuing & Bridging).
This subject is a little confusing and requires some reading. There is a
good chapter on it in Caslow's BRS book.
Good Luck,
