I'm having a bit of trouble with this task which is a redistribution task. You have to redistribute on two devices between rip and ospf. Classic loop scenario with a twist. The twist is that the loopbacks are already redistributed into RIP as connected routes.
Seems like I should be able to tag and filter this loop issue so I write a route-map and apply it to R7 and R8 and reference it in my redistribution statements. route-map R2O deny 10 match tag 110 route-map R2O permit 20 set tag 120 ! route-map O2R deny 10 match tag 120 route-map O2R permit 20 set tag 110 I've run into an issue where debug ip routing shows theses loopbacks as flapping. *Jul 27 02:21:55.426: RT: NET-RED 166.7.7.7/32 *Jul 27 02:21:55.430: RT: NET-RED 166.8.8.8/32 So then I consulted the solutions guide, and that's when I got really confused. First I believe there is a major error in that they apply a redistribute connected route-map that seems like it would overwrite the route-map from the previous task, that redistributed 166.7.7.7 and 166.8.8.8 into RIP in the first place. This clearly violates the earlier task. Second they write a convoluted route-map tagging the routes differently on the two routers.. Now I am not sure what the purpose of this is, but when I tried it I had even more routes looping. Are they just trying to be a bit fancy here or is there a reason to tag the routes differently on the two routers?
