All P580 and P882 Multiservice switches can be configured as an IP, IPX,

and AppleTalk router with virtual interfaces. Virtual interfaces are mapped

to physical ports or VLANs. Layer 3 IP traffic is routed between the virtual

Ports become members of VLANs by being assigned or by rules. Multiple

VLANs can share a single trunk port. In contrast, multiple physical ports

can be associated with a single VLAN. In all cases, traffic that arrives and

leaves the same VLAN is bridged, not routed.

This section provides the following sections:

Compatibility with Layer 2 Modules

Routing with Layer 2 and Layer 3 Modules

Each switch is completely backward compatible with all of the layer 2

media modules that the switch currently supports. Layer 3 traffic is routed

by sending that traffic to the supervisor module. The supervisor module

routes all traffic from layer 2 media modules as described in the next

"Routing with Layer 2 and Layer 3

* Note: Layer 2 traffic that does not require routing is bridged

independently of the layer 3 traffic based on the MAC address

or VLAN information.
