I want EIGRP to pick the MPLS not the DMVPN but it doesn't

the MPLS is 10.66.0.1 it has better everyting but is still not preferred because of the "external" I think.

Can someone tell me how to make it the preferred route?

Re: I want EIGRP to pick the MPLS not the DMVPN but it doesn't

Hello Brent,

>> Can someone tell me how to make it the preferred route?

you should use a second EIGRP process for the DMVPN cloud and then you should redistribute it into main EIGRP process in order to change EIGRP routes coming from DMVPN EIGRP external too.

OR if this is an MPLS L3 VPN service you should check with MPLS SP if you can use EIGRP as PE-CE routing protocol instead of eBGP that you are probably using now. In these way EIGRP routes coming from the MPLS L3 VPN can appear as internal routes instead of external routes and they could be preferred over routes coming from DMVPN cloud.

Second approach requires cooperation of SP and may lead to additional fees on the MPLS service.

First approach has a greater impact as you need to change EIGRP AS numbers on several routers but it is totally under your control.

Hope to help

Giuseppe
