Feature Highlights of ExtremeWare XOS 11.1
Virtual Routers
NOTE
Although the Aspen 8810 switch supports the three system virtual routers (VR-Default, VR-Mgmt, VR-Control), the
BlackDiamond 10K switch additionally supports user-created 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. Because 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. In
this release of ExtremeWare XOS, the management port belongs to one virtual router and all other ports
belong to other virtual routers.
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
