If you want to send certain routes to one neighbor but not another, you must
apply an outbound prefix list filter to the neighbor. (See "Creating Prefix Lists:
Configuring Filters for Route Exchange" on page 13-78 or "Defining the Routes
that a Router Can Advertise" on page 13-89.)

Setting the Router ID

The BGP interface identifies itself to neighbors with its router ID. Often this
ID is the IP address of the logical interface that connects to each neighbor. It
can also be the address of a loopback interface used as the update source.
(Having a loopback interface as the update source ensures that a BGP session
stays open even if one connection goes down.)
To specify the router ID, enter the following command from the BGP config-
uration mode context:
Syntax: bgp router-id <A.B.C.D>
For example:
ProCurve(config-bgp 1)# bgp router-id 10.1.1.1

Configuring a BGP Neighbor

BGP is different from many routing protocols because it does not allow a
router to automatically search for peers from which to obtain routes. You must
configure a separate BGP neighbor for each router with which the local router
can communicate. For each neighbor, you can configure a policy to dictate
which routes the BGP interface sends to and accepts from the neighbor.

Setting the BGP Neighbor ID

BGP identifies a peer router by its IP address. You set the neighbor's ID when
you create the policy for it. Enter this command from the BGP configuration
mode context:
Syntax: neighbor <neighbor A.B.C.D>
For example, enter the IP address of your ISP router:
ProCurve(config-bgp 1)# neighbor 1.1.1.1
