Hi Giuseppe,   I solved the problem. The problem is about the ADs of protocols. EBGP:20 EXT EIGRP:170 IBGP:200 Once the Hub1 MPLS Down, Hub2 MPLS becomes primary. It gets the route from EBGP and redist it into EIGRP. Thus HUB1 learns it via EIGRP since its AD is lower than IBGP. Once HUB2 MPLS becomes down as well, the route is still on its Routing Table, It continues to redist it to EIGRP and HUB2 continues to learn it via EIGRP. Thus one redist is possible, DC router doesn't have a chance to learn lower seed metric route from HUB1. Solution: I lowered IBGP AD below Ext EIGRP to force HUB1 to learn it from IBGP. Thus the process becomes opposite and HUB1 can redist it to EIGRP. Then DC router learns it from HUB1.   I used this technic before to solve the same problem but without the route-map for seed metric, it didn't work properly. Now a combination of two technics resolved my problem. Thank you for the EIGRP command, it made me sure that seed metrics configured and redistributed properly for EBGP and IBGP learned routes.   Thank you for your replies.   Regards, Umut Yasar     ...

Hi Giuseppe,   After testing several times I found out that when Hub1 MPLS and Hub2 MPLS links both down, the return path from DC choosing Hub2, even if it has a higher metric. Once I clear both Hub1 and Hub2 Eigrp neighbors, Hub1 becoming return path. Do you have any idea about the cause of this?   Below is from DC router once the Hub2 become return path P 192.168.x.0/24, 1 successors, FD is 768256, tag is A via a.a.a.1 (768256/768000), VlanZ   Below is from DC router once the Hub1 become return path after resetting eigrp neighbor P 192.168.x.0/24, 1 successors, FD is 512256, tag is A via a.a.a.2 (512256/512000), VlanZ, serno 2361     ...

Hi Giuseppe,   Yes, As I mentioned in the previous reply  I created a very similar access-list and route map as yours after I asked you :) Different from yours I used default-metric for the EIGRP and for the IBGP routes I used access-list as well for the next-hop. Sometimes when a person asks the question he finds the answer afterward by himself.   I tested it and it's working. But thank you for your reply anyway. The prefix-list for spoke-routes is a good idea to control redist to eigrp, I plan to use this.   Regards,   Umut Yasar     ... View more

Hi  Giuseppe,   I think I figured it out. I tried the route-map and it's working. I didn't use default-metric instead I used what I mentioned previously to set metric and just edited it for IBGP learned routes with higher seed metric as I mentioned before. I think this is just another way of setting a metric. But I'll change it to default-metric as I read it's best-practice when redistributing the routes.   I used 10000 for min bandwidth for all route map and just changed delay, different from your example. I think it's ok as well, just used delay for changing the distance calculation.  I reckon this metric is nothing to do with actual min bandwidth of the route as it's for redistribution.   Regards, Umut ...

Hi Giuseppe,   Thank you for your reply. I think you got what I need in your comment below:   >>"To be noted the route-maps BGP-into-EIGRP must take in account if the routes are learned via eBGP or via iBGP and set a seed metric accordingly. This can be done by checking the BGP next-hop."   I was trying to do it for some time but I couldn't find a way how to check BGP next-hop and apply different metrics to EBGP learned routes and IBGP learned routes in Hub1 and Hub2.   I want to apply for instance like below, I know I need to check next-hop (ebgp/ibgp learned) and apply seed metrics accordingly in a route map since two commands can not be active at the same time in a router, I wrote  it as a reference for seed metric sequence for redundancy I want to use. But I couldn't figure out how to do it in cisco router. I can use default metric as well as you mentioned in your email, but again how to change seed metrics according to next-hop in a route map? Could you give an example config?   HUB1 EIGRP 100 redistribute bgp 65000 metric 10000 1 255 1 1500 route-map BGP_TO_EIGRP (for EBGP primary MPLS link) ! redistribute bgp 6500 metric 10000 200 255 1 1500 route-map BGP_TO_EIGRP (for IBGP DMVPN01 tunnel)   HUB2 EIGRP 100 redistribute bgp 65000 metric 10000 100 255 1 1500 route-map BGP_TO_EIGRP (for EBGP secondary MPLS link) ! redistribute bgp 6500 metric 10000 1000 255 1 1500 route-map BGP_TO_EIGRP (for IBGP DMVPN02 tunnel)   Regards,   Umut   ...
