Two separate MPLS WAN link with two separate providers and two separate routers

[Spencer.colvin21]

I have two WAN routers coming from my two core switches going to separate providers and then across to our backup data center. we are running BGP externally and EIGRP internally. I want all my traffic to run over one circuit and specific replication traffic to use the other. I am wondering how to set up my distribution so that my backup circuit will take it own link and stop using EIGRP across the other circuit as well as force specific replication traffic to only use that backup link. any config advise would help!

I have temporarily changed the metric for the backup link so that it wont be used.

main:  redistribute bgp 65205 metric 100000 100 255 1 1500

backup:  redistribute bgp 65202 metric 10000 100 200 1 1500

Have a look at this link. You have to use route maps to send certain subnets out to spesific providers.

Would it be the same set up if I am running EIGRP internally and not IBPG?

[Spencer.colvin21]

I would need to redistribute BGP into EIGRP and visa versa

BTW, another approach you might consider, instead of trying to map traffic to specific paths, would be to use QoS on both paths to control how traffic is prioritized.  Works especially well with PfR, so that all your traffic can take fully advantage of all your WAN bandwidth.

I am only trying to have specific IP addresses go across the backup circuit though. would QoS support that?

[Joseph W. Doherty]

No, but QoS can determine how traffic for specific IP addresses is treated as is goes across a circuit.

Again, the ideal is, you don't have purpose dedicated circuit(s), but you have instead, purpose dedicated traffic treatment(s).
