2 Routers same svi question

Answered Question
Oct 13th, 2007

I see this config and am wondering if this is an incorrect configuration.

I have 2 x layer 3 switches connected together via a trunk. Both of these switches have:

"Int vlan 200" setup with different IP addresses on the same segment/subnet

Is it ok to have these svi's setup like this? I'm asking this mainly becasue I am fiddling with an eWan config.

I'm used to have a single svi setup on a single router and that being the default gateway for that svi vlan.

Can someone please advise?

I have this problem too.

Yes, it's ok to have two switches using the same SVI with different IP address. Usually, that's done when configuring the management interface on your switches. You can have all switches using Vlan200 (common subnet) and that Vlan would be your management IP, not to be used for clients.

You can also have the clients use that IP address as default gateway, I don't see a problem with that.
