A present network scenario, i have a core router (VXR A) with a link connected to MPLS network M-1 Router an e-BGP (instance X), all the customer connected to MPLS network uses instance X of M-1 to VRX A for Internet reach ability.
Now changed for high availability network, i will be adding new Core Router VXR B. For this, VXR B will also be connected with MPLS network M-1 router an e-BGP (Instance Y), we have numbers of customer connected to our MPLS network example Customer A and Customer B, my requirement is that both the instance M-1 to VXR A and M-1 to VRX B should be on Active that means Customer A should be going through Instance X and Customer B should be going through Instance Y. In case of link failure between any VXR (A and B) to M-1, route of any customers should be going through the live one instance.
Here by I have also attached the network diagram.
Hopping for your help for implementing such network scenario.
