Local preference attribute
You can change the value of the LOCAL_PREFERENCE attributes for all routes the router receives. To change the LOCAL_PREF value in
ROUTER-BGP mode from 0 to 4294967295 with default 100, use the default local preference value command.
To view the BGP conguration, use the show running-configuration command. A more exible method for manipulating the
LOCAL_PREF attribute value is to use a route-map.
1 Assign a name to a route map in CONFIGURATION mode.
route-map map-name {permit | deny | sequence-number}
2 Change the LOCAL_PREF value for routes meeting the criteria of this route map in ROUTE-MAP mode, then return to
CONFIGURATION mode.
set local-preference value
exit
3 Enter ROUTER-BGP mode.
router bgp as-number
4 Enter the neighbor to apply the route map conguration in ROUTER-BGP mode.
neighbor {ip-address}
5 Apply the route map to the neighbor’s incoming or outgoing routes in ROUTER-BGP-NEIGHBOR-AF mode.
route-map map-name {in | out)
6 Enter the peer group to apply the route map conguration in ROUTER-BGP mode.
template {ip-address} route-map map-name {in | out}
7 Apply the route map to the peer group’s incoming or outgoing routes in ROUTER-BGP-NEIGHBOR-AF mode.
route-map map-name {in | out}
8 Save the conguration.
