Configuring BGP 45.4
The chapter describes how to configure the Boundary Gateway Protocol (BGP). For details about BGP
commands, refer to section “BGP Commands”. BGP is an Exterior Gateway Protocol (EGP) defined in
RFC1163, 1267 and 1771. BGP allows to create a routing selection mechanism among the autonomous
systems. The routing selection mechanism can ensure automatic exchange of routing selection information
among the auto-managed system without loop.
45.4.1 Overview
45.4.1.1 BGP Introduction
In BGP, each route contains a network number, auto-managed system list that the route passes (as-path) and
other attribute lists. Our switch software supports version 4 BGP defined in RFC1771. The basic function of
BGP is to exchange network reachable information with other BGP systems, including information about the
AS routing table. The information about AS routing table can be used to construct the AS connection figure
and apply AS-level routing strategy through the AS connection figure. BGP Version 4 supports CIDR. CIDR
reduces the size of the routing table by creating the summary route. The super network, therefore, is
generated. CIDR cancels the notion of BGP network class and supports IP prefix broadcast. The CIDR can be
transmitted through OSPF, enhanced IGRP, ISIS-IP and RIP2.
