I'm working on this ticket right now and looking at your route-maps it may work but you have 1 extra statements in each for dealing with redistribution between 3 routing protocols. The way I built mine for this ticket were identical to Marko's in the video solution to the lab. The way I think of it is:
1st statement - deny tags with the AD of the destination routing protocol 2nd statement - match and tag the protocol that isn't involved in that particular route-map with its own AD 3rd statement - tag the source routing protocol with its own AD route-map OSPF-2-RIP deny 10 match tag 120 ! route-map OSPF-2-RIP permit 20 match tag 90 set tag 90 ! route-map OSPF-2-RIP permit 30 set tag 110 ! ! ! route-map OSPF-2-EIGRP deny 10 match tag 90 ! route-map OSPF-2-EIGRP permit 20 match tag 120 set tag 120 ! route-map OSPF-2-EIGRP permit 30 set tag 110 ! ! ! route-map RIP-2-EIGRP deny 10 match tag 90 ! route-map RIP-2-EIGRP permit 20 match tag 110 set tag 110 ! route-map RIP-2-EIGRP permit 30 set tag 120 ! ! ! route-map RIP-2-OSPF deny 10 match tag 110 ! route-map RIP-2-OSPF permit 20 match tag 90 set tag 90 ! route-map RIP-2-OSPF permit 30 set tag 120 ! ! ! route-map EIGRP-2-RIP deny 10 match tag 120 ! route-map EIGRP-2-RIP permit 20 match tag 110 set tag 110 ! route-map EIGRP-2-RIP permit 30 set tag 90 ! ! ! route-map EIGRP-2-OSPF deny 10 match tag 110 ! route-map EIGRP-2-OSPF permit 20 match tag 120 set tag 120 ! route-map EIGRP-2-OSPF permit 30 set tag 90 On Wed, Sep 22, 2010 at 9:26 PM, Jason Maynard <[email protected]>wrote: > > > Hey guys can you confirm whether my route-map works and ensures not loops > could form.
