Multiple content switches on same subnet

[rhholmes]

Can anyone confirm if there is an issue having two pairs of content switches (11500s) on the same subnet? The circuit addressing, interface redundancy and VIPs all use the same subnet. Wondering if there would be any issues with the redundancy, arps, etc.. Am stuck with this arrangement during the migration phase of the project.

Appreciate your input.

Rob,

they can be on the same subnet but they must use different VIP ip addresses.

For the VRRP protocol, you should use different group number on each pair to avoid collision.

Otherwise, that is no problem. I have many pairs like this in the lab sharing the same subnets and this is ok.
