Challenges in traditional Layer 2 VPN: Flooding Behavior. Using the 'network statement' method works, but not the redistribution method. Therefore R2 will not redistribute these routes from EIGRP to OSPF, resulting in only one path used. Currently we are only redistributing ospf process 2 into ospf process 1 (1 = core backbone). How do I redistribute connected routes into an OSPF instance on a Nexus 7010 with a defined metric? A. The redistribution uses route-map to evaluate community associated with the routes. You need OSPF on both of the routers and you need to advertise the networks connected to the respective routers for OSPF to work. Skandarajah has 5 jobs listed on their profile. Using the 'network statement' method works, but not the redistribution method. Just move to Nexus for core nice large one, then the distribution smaller but also nexus. I have a topology like this  I have 3 routers: router r1 connect to router r2 and run ospf area 23. The network in the picture above is fairly simple. At this point R2 should have. This feature is unsupported, but it works. To remove the redistribute command from the configuration file and restore the system to its default condition in which the software does not redistribute routes, use the no form of this command. i don't have a need for redistributing from 1 process to another. I think you can simplify your route-map, if you want to redistribute every connected subnet and static route. The following are the configs:. I also thought of adding another ospf area number 3 and connect it to area 1 where then we would have discontiguous areas ! and for a fix we would have to use either GRE Tunnel or Virtual Link but as you can see I did not do it just to avoid having too many devices to work with and Virtual link and GRE Tunnel I will explain in another post. --> First of all we need to see whether the router is sending / receiving hello messages.
