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.
Changing the NEXT_HOP Attribute
You can change how the NEXT_HOP attribute is used.
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 as the next hop for a BGP neighbor.
CONFIG-ROUTER-BGP mode
neighbor {ip-address | peer-group-name} next-hop-self
• Sets the next hop address.
