Hi


I've got a switch with about 70 vlan's and 3 loopback interfaces on it, the switch also does routing. I want to telnet to a device on vlan 66, how do I know what ip the switch is going to use as the source ip address if I initiate the telnet from the switch?


Thanks

Dan

I believe it uses the closest interface to the destination (per the routing table). You can always source from an interface if you need to.
