Hi, hoping that somebody can advise some options for this situation we have a requirement for.
We are setting up a network for a customer, they currently have 2 x RB1100AHx2 routers to act as their core routers and want to use 2 for redundancy purposes.
The issue is that they have a layer 2 connection coming in from a supplier and get handed off vlans from that supplier, normally they would just terminate the vlan on the router and add layer 3 IP to it and away they would go.
However, they want to be able to provide redundancy for these vlans from this supplier across the 2 core routers, in some cases they only need to bridge the vlan onwards to another router, it just depends on whether they can terminate the IP on the main router or another edge router, often it ends up being another router.
Unfortunately I'm not an expert in layer 2 redundancy, and whilst I would be OK to do something if it were only layer three we had to terminate, I am unsure of the correct approach when dealing with layer 2 vlan redundancy.
If anybody could suggest some options of how we might be able to tackle this for the customer that would be appreciated.
