Wondering if some gurus can help me plan this in my head.
I understand how MPLS and VPLS tunnels work over an OSPF infrastructure and I plan to test and implement this in my OSPF network soon.
I am wanting to move to PPPoE as well and like the idea of having a central PPPoE server connected to the CPE via a VPLS tunnel.
My question is how to make this redundant.
OSPF does an awesome job of making the network redundant but what good is this if the the VPLS tunnel terminates on a single router and a single PPPoE server.
I plan to use Mikrotik as my PPPoE Concentrator and would like to have at least one backup PPPoE Concentrator
Can someone explain how this would be setup? bridging VPLS tunnels? split horizon bridging? these are all things I am not sure if are required to make this work.
