I have a DS3 circuit to our DR site that currently carries our Voice and data traffic to DR along with our replication traffic.
The voice is bridged to DR, but the data and replication is routed via BGP, then distributed into OSPF locally at each site.
I would like to add a second DS3 to give the replication traffic it's own link to the DR site.
This would mean I would have two seperate routed connections to DR.
What would be the best way to ensure the replication traffic uses the new DS3 and everything else uses the other DS3?
Since I am distributing BGP into OSPF, would it be best to use PBR, or utilize BGP to make these decisions?
Also, I would like to have everything use one link or the other if one of them fails.
