• Change the LOCAL_PREF value.
CONFIG-ROUTER-BGP mode
bgp default local-preference value
•
value
: the range is from 0 to 4294967295.
The default is 100 .
To view the BGP configuration, use the
show config
command in CONFIGURATION ROUTER BGP mode or the
show running-
config bgp
command in EXEC Privilege mode.
A more flexible method for manipulating the LOCAL_PREF attribute value is to use a route map.
1 Enter the ROUTE-MAP mode and assign a name to a route map.
CONFIGURATION mode
route-map map-name [permit | deny] [ sequence-number ]
2 Change LOCAL_PREF value for routes meeting the criteria of this route map.
CONFIG-ROUTE-MAP mode
set local-preference value
3 Return to CONFIGURATION mode.
CONFIG-ROUTE-MAP mode
exit
4 Enter ROUTER BGP mode.
CONFIGURATION mode
router bgp as-number
5 Apply the route map to the neighbor or peer group’s incoming or outgoing routes.
CONFIG-ROUTER-BGP mode
neighbor { ip-address | peer-group-name } route-map map-name {in | out}
To view the BGP configuration, use the show config command in CONFIGURATION ROUTER BGP mode. To view a route map
configuration, use the
show route-map
command in EXEC Privilege mode.
Configuring the local System or a Different System to be the
Next Hop for BGP-Learned Routes
You can configure the local router or a different router as the next hop for BGP-learned routes.
To change how the NEXT_HOP attribute is used, enter the first command. To view the BGP configuration, use the
show config
command in CONFIGURATION ROUTER BGP mode or the
show running-config bgp
command in EXEC Privilege mode.
You can also use route maps to change this and other BGP attributes. For example, you can include the second command in a route map to
specify the next hop address.
• Disable next hop processing and configure the router (route reflector) as the next hop for a BGP neighbor.
CONFIG-ROUTER-BGP mode
neighbor { ip-address | peer-group-name } next-hop-self [all]
