Chapter 6 Configuring Advanced BGP
Configuring Advanced BGP
This example shows how to configure a BGP peer-policy template and apply it to a BGP peer:
switch# configure terminal
switch(config)# router bgp 65536
switch(config-router)# template peer-session BasePolicy
switch(config-router-ptmp)# maximum-prefix 20
switch(config-router-ptmp)# exit
switch(config-router)# neighbor 192.168.1.1 remote-as 65536
switch(config-router-neighbor)# address-family ipv4 unicast
switch(config-router-neighbor-af)# inherit peer-policy BasePolicy
switch(config-router-neighbor-af)# copy running-config startup-config
Configuring BGP Peer Templates
You can configure BGP peer templates to combine session and policy attributes in one reusable
configuration block. Peer templates can also inherit peer-session or peer-policy templates. Any attributes
configured for the neighbor take priority over any attributes inherited by that neighbor from a BGP
template. You configure only one peer template for a neighbor, but that peer template can inherit
peer-session and peer-policy templates.
Peer templates support session and address family attributes, such as eBGP multihop time-to-live,
maximum prefix, next-hop self, and timers.
BEFORE YOU BEGIN
Ensure that you have enabled the BGP feature (see the “Enabling the BGP Feature” section on
page 5-11).
Note When editing a template, you can use the no form of a command at either the peer or template level to
explicitly override a setting in a template. You must use the default form of the command to reset that
attribute to the default state.
