Chapter 7. Border Gateway Protocol and Enterprise Routing Policy
This chapter reviews the Border Gateway Protocol (BGP) version 4 operation and key attributes to accommodate a detailed discussion of BGP enterprise applications. BGP is all about the control of routing information between autonomous systems (ASs). Emphasis is placed on the use of routing policy to facilitate load balancing and common enterprise applications of inbound and outbound routing requirements when customers are dual-homed to different service providers. The topics covered include:
BGP overview and enterprise applications
External BGP (EBGP) peering with asymmetric load balancing
BGP policy for the enterprise
BGP dual-homing scenario with route reflection and outbound policy
Implementation of a dual-homed inbound policy by manipulating BGP attributes
Juniper Networks routers offer extensive feature support for BGP. In fact, the list of supported standards is too long to be valuable here. Consult the BGP overview in the Junos documentation to confirm the list of supported RFCs and drafts for your particular Junos software release.
