Virtual Routers
ExtremeWare XOS supports virtual routers. This capability allows a single physical switch to be split
into multiple virtual routers. This feature separates the traffic forwarded by a virtual router from the
traffic on a different virtual router. Each virtual router maintains a separate logical forwarding table,
which allows the virtual routers to have overlapping address spaces. Since each virtual router maintains
its own separate routing information, and switch ports can belong to one and only one virtual router,
packets arriving at a port on one virtual router can never be switched to the ports on another. With
multiple virtual routers contained on a single physical switch, some commands in ExtremeWare XOS
now require you to specify to which virtual router the command applies. For example, when you use
the ping command, you must specify from which virtual router the ping packets are generated. Many
commands that deal with switch management use the management virtual router by default.
