Chapter 19

Configuring BGP4

This chapter provides details on how to configure Border Gateway Protocol version 4 (BGP4) on Foundry

products using the CLI and the Web management interface. BGP4 is supported on the following Foundry

products:

• NetIron Internet Backbone router

• BigIron Layer 3 Switch

• NetIron stackable Layer 3 Switch (must have 32MB RAM and 4MB flash module)

• TurboIron/8 Layer 3 Switch

NOTE: BGP4 is not supported on the FastIron II.

BGP4 is described in RFC 1771. The Foundry implementation fully complies with RFC 1771. The Foundry 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 19-88.

This chapter shows the commands you need in order to configure the Foundry Layer 3 Switch for BGP4. For a

detailed list of all CLI commands, including syntax and possible values, see the Foundry Switch and Router

Command Line Interface Reference.

NOTE: Your Layer 3 Switch’s management module must have 32MB or higher to run BGP4.

NOTE: The TurboIron/8, NetIron stackable, and BigIron Layer 3 Switches using basic management modules

(not Management II or higher) can contain 10,000 routes by default. If you need to increase the capacity of the IP

route table for BGP4, see “Displaying and Modifying System Parameter Default Settings” on page 10-70.
