"and
IP Forwarding turned on" is the operant condition.
Switches don't forward between IP addresses; they forward between the
incoming port which has an IP address and all the Level 2 ports which have no
IP address.

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?
