Kindly requesting your inputs, here is a situation. I have a customer with a Hub site and 2 spoke sites connected over an IP/MPLS VPN network.
Each site (Hub and Spoke) has 2 CE routers connected to 2 different MPLS VPNs from the same provider (can connect to a same PE or different PEs)
I want to know how I can achieve hot standby for both the VPNs in other words I want an "active-active" configuration.
How can I do it any ideas??
I am looking at iBGP... would be glad if anyone can share some existing and proven ideas.
