Chapter 6: BGP Configuration Guide

Notes on Using the AS Path Prepend Feature

Use the as-countoption for external peer-hosts only.

If the as-countoption is entered for an active BGP session, routes will not be resent to reflect the new setting. To have routes reflect the new setting, you must restart the peer session. To do this:

a.Enter Configure mode.

b.Negate the command that adds the peer-host to the peer-group. (If this causes the number of peer-hosts in the peer-group to drop to zero, then you must also negate the command that creates the peer group.)

c.Exit Configure mode.

d.Re-enter Configure mode.

e.Add the peer-host back to the peer-group.

If the as-countoption is part of the startup configuration, the above steps are unnecessary.

BGP Configuration Examples

This section presents sample configurations illustrating BGP features. The following features are demonstrated:

BGP peering

Internal BGP (IBGP)

External BGP (EBGP) multihop

BGP community attribute

BGP local preference (local_pref) attribute

BGP Multi-Exit Discriminator (MED) attribute

EBGP aggregation

Route reflection

BGP Peering Session Example

The router process used for a specific BGP peering session is known as a BGP speaker. A single router can have several BGP speakers. Successful BGP peering depends on the establishment of a neighbor relationship between BGP speakers. The first step in creating
