Riverstone Networks RS 32000 Switch Router Getting Started Guide 2-3

Introduction Software Overview

2.3 SOFTWARE OVERVIEW

This section describes the features and capabilities of the RS 32000 in greater detail.

2.3.1 Bridging

The RS provides the following types of wire-speed bridging:

Address-based bridging – The RS 32000 performs this type of bridging by looking up a packet’s destination address

in an L2 lookup table on the line card that received the packet from the network. The L2 lookup table indicates the exit

port(s) for the bridged packet. If the packet is addressed to the router’s own MAC address, the packet is routed rather

than bridged.

Flow-based bridging – The RS 32000 performs this type of bridging by looking up a packet’s source and destination

address in an L2 lookup table on the line card that received the packet from the network.

Your choice of bridging method does not affect RS 32000 performance. However, address-based bridging requires

fewer table entries. Alternately, while flow-based bridging uses more table entries, it provides tighter management and

control over bridged traffic, and greater resolution to RMON I statistics.

The RS ports perform address-based bridging by default, but can be configured to perform flow-based bridging on a

per-port basis. A port cannot be configured to perform both types of bridging at the same time.

2.3.2 Port and Protocol VLANs

The RS supports the following types of Virtual LANs (VLANs):

Port-based VLANs – A port-based VLAN is a set of ports that comprises a layer-2 broadcast domain. The RS confines

MAC-layer broadcasts to the ports in the VLAN on which the broadcast originates. RS ports outside the VLAN do not

receive the broadcast.
