Before You Configure BGP
Before you attempt to configure BGP, you should have TCP/IP reachability to the BGP peers with which you want your system to communicate. This may include tasks such as setting up interfaces and creating routes.
Refer to the ERX Physical and Link Layers Configuration Guide for information on how to configure appropriate interfaces. Refer to ERX Routing Protocols Configuration Guide, Vol. 1, Chapter 1, Configuring Routing Policy, for information on setting up routing information.
