Configuring BGP4

This chapter provides details on how to configure Border Gateway Protocol version 4 (BGP4) on HP products using the CLI and the Web management interface. BGP4 is supported on the following HP products:

•HP 9308M and HP 9304M routing switches

•HP 6308M-SX routing switch

NOTE: BGP4 is not supported on the HP 6208M-SX.

BGP4 is described in RFC 1771. The HP implementation fully complies with RFC 1771. The HP BGP4 implementation also supports the following RFCs:

•RFC 1745 (OSPF Interactions)

•RFC 1965 (BGP4 Confederations)

•RFC 1997 (BGP Communities Attributes)

•RFC 2385 (TCP MD5 Signature Option)

•RFC 2439 (Route Flap Dampening)

•RFC 2796 (Route Reflection)

•RFC 2842 (Capability Advertisement)

To display BGP4 configuration information and statistics, see “Displaying BGP4 Information” on page 10-84.

This chapter shows the commands you need in order to configure the HP routing switch for BGP4. For a detailed list of all CLI commands, including syntax and possible values, see the Command Line Interface Reference.

NOTE: Your routing switch’s management module must have 32MB or higher to run BGP4.

NOTE: The HP 6308M-SX and HP 9304M or HP 9308M routing switches using non-redundant management modules can contain 10,000 routes by default. If you need to increase the capacity of the IP route table for BGP4, see the “Displaying and Modifying System Parameter Default Settings“ section in the “Configuring Basic Features“ chapter of the Installation and Getting Started Guide.

Overview of BGP4

BGP4 is the standard Exterior Gateway Protocol (EGP) used on the Internet to route traffic between Autonomous Systems (AS) and to maintain loop-free routing. An autonomous system is a collection of
