Dustin,
Try this:
Debug ip rip
Watch what your router sends out and then you will know.

Hi Luis,
Yes, you are right rip v1 is not in the test anymore. I'm just throwing
quesiton out incase we may get something ugly. How do you advertise a
summary address out to your RIP neighbor if neither using ip
summary-address rip in the interface nor auto-summary in the router
mode? Dustin
