RE: [nv-l] Routers vs. Switches

How would NV then be able to differentiate between an actual router and a switch that happens to have a primary and secondary interface.  Since Switches generally only have one IP address (in our case two for redundancy) it will always consider these to be routers then I take it?

Almost everything IP has a routing table including your desktop.  Issue "route print" to see it. 
 
NetView considers anything which has multiple IP addresses and IP Forwarding turned on to be a router.

Hello all,


Its it my understanding that a device is considered a router if it has a routing table?   What I am trying to find out is how to differentiate a switch from a router.  I use routers as gateways, however switches are not gateways.  But if NV comes across a switch which happens to have a routing table (Such as a switch with an L3 card in it) it will interpret that device as a router and place it as a gateway?
