Hi.
I will be replacing an old set of switches with a pair ex4300s in VC with AFL and EFL . This switches connectivity to the rest of the network is via two circuits running BGP to layer3 switch interfaces, both circuits are on the same VPLS.
What I'm wondering though is can I have two layer 3 interfaces within the same subnet on two separate interfaces for redundancy. So in the event circuit A which has 10.50.20.1/27 ip on the interface drops, the BGP peering on circuit B with ip interface 10.50.20.2/27 would be used to reach sites A to D
From a config point of view the switch thinks this is fine but I can't actually test it until I'm on site.
Below is a diagram, showing what I want to achieve. I know it will work if I do make the switches into a VPC and run iBGP between the two switches but I would prefer to use the VC if possible.
I am open to any other suggestions, please note I can not change the IP subnet for the VPLS as it would require changing multiple sites
Thanks
