I have two new 3850 24 port gig switches. I am putting one in the front wiring closet of our warehouse, the other in the rear.
IS there a way to have these be a layer 2 / layer 3 Virtual Switch using VSS?
I was looking at creating a cross-stack etherchannel. But didn't know what that really would do regarding layer 2/ layer 3 redundancy, if any. I have DHCP, a few VLANs, and inter vlan routing configured.
Was hoping that there was some way to do this so that if one switch failed, the other would still provide inter-vlan routing.
Let's say I have VLAN 2. I assign 3850-1 a port in VLAN 2 with IP 192.168.1.1.
Let's say I have 3850-2 and I have an ether channel.
If 3850-1 goes down, I want 3850-2 to be able to still route for VLAN 2 as the default gateway for that VLAN.
It's almost like having a virtual IP for the default gateway IPs for each VLAN and having one switch have the active role on it, and if that switch failes, to have the other switch take that VIP and continue to provide basic intervlan routing.
Perhaps put differently, how can I have the two switches provide inter-vlan routing redundancy?
