IP routing 17
As with any IP address, virtual router interface addresses are also used for
device management. For management over IP, any virtual router interface
IP address can be used to access the switch as long as routing is enabled.
When the Nortel Ethernet Routing Switch 5500 Series switch or stack is
used without routing enabled, the Management VLAN is reachable only
through the switch or stack IP address. With IP routing enabled on the
switch or stack, any of the virtual router IP interfaces can be used for
management over IP.
Once routing is enabled on the Nortel Ethernet Routing Switch 5500 Series
switches, the Management VLAN behaves like all other routable VLANs.
The IP address is reachable through any virtual router interface, as long as
a route is available. Actually, all virtual router interfaces can be used as the
Management VLAN over IP.
Multinetting
The Nortel Ether net Routing Switch 5500 Series supports the definition
and configuration of up to eight secondary interfaces on each VLAN
(multinetting). With IP multinetting, you can associate multiple IP subnets
with one VLAN. That is, connected hosts can belong to different IP subnets
on the same VLAN.
Multinetting can be configured using the CLI or the Device Manager.
The following diagram illustrates a network with configured IP multinetting.
