Routing Overview
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
interfaces.
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:

Routing with Layer 2 and Layer 3 Modules
Compatibility with Layer 2 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
section, “
Routing with Layer 2 and Layer 3 Modules .”
* 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.
