Gang,
I have a bisic coniguration for routing rip but when I do a sh ip route rip or sh ip route the table is empty as far as rip (R) updates go. I thought I would except to show R on the route table as the networks are connected. When I looked at the debug, shown below, and see that the e0 is sending but the receiving updates are getting suppressed ...null update. I cant figure out why this is happening can anyone put some light on the subject. Also the routing table below just shows the networks connected, networks on each router....router a and router b. See the show run below ios 12.x for all routers.
I did not give the other router's config as the are the same except for the ip address which is 192.168.0.100 /24 on the othe routers e0
Router A
