Can someone please point me in the right direction for the following scenario.
We have a primary link into a BT MPLS cloud. At a branch site we have a router with the branch network on one I/F and a DR LAN on a second I/F(this is a mirror of the primary site address).
BGP ensures that traffic is routed to the primary site under normal circumstances.
The problem is that when we connect the DR LAN at the branch site, the branch network prefers this route to the one back at the primary site over the MPLS cloud.
BT have mentioned that they use 'route map barring' in their managed WAN solution, but can't help us beyond that.
