MOT(config-bgp)#neighbor 3.3.3.1 weight 1000

Using a Route Map
The commands in the following example configure Router Los Angeles using a route
map. In the commands to configure Router Los Angeles, Instance 10 or route map 10
assigns a weight of 1000 to any updates from AS 100. Instance 20 assigns a weight of
500 to updates from any other AS.
Example
MOT(config)#router bgp 400
MOT(config-bgp)#neighbor 3.3.3.1 remote-as 100
MOT(config-bgp)#neighbor 3.3.3.1 route-map 10 in
MOT(config-bgp)#neighbor 4.4.4.1 remote-as 300
MOT(config-bgp)#neighbor 4.4.4.1 route-map 10 in
MOT(config-bgp)#exit
MOT(config)#ip as-path access-list 1 permit ^100
MOT(config)#route-map 10 permit 10
MOT(config)#match as-path 1
MOT(config)#set weight 1000
MOT(config)#route-map 10 permit 20
MOT(config)#set weight 500
Using an AS Path Access List
The commands in the following example configure Router Los Angeles using an AS
path access list. Filter List 1 assigns a weight attribute of 1000 to updates received
from neighbors from AS 100. Access List 1 permits any update whose AS-path
attribute begins with 100 (specified by “^”). The same is true for Access List 2
regarding AS 300. Filter List 2 assigns a weight attribute of 500 to updates received
from AS 300.
Example
MOT(config)#router bgp 400
MOT(config-bgp)#neighbor 3.3.3.1 remote-as 100
MOT(config-bgp)#neighbor 3.3.3.1 filter-list 1 weight 1000
MOT(config-bgp)#neighbor 4.4.4.1 remote-as 300
MOT(config-bgp)#neighbor 4.4.4.1 filter-list 2 weight 500
MOT(config-bgp)#exit
MOT(config)#ip as-path access-list 1 permit ^100
MOT(config)#ip as-path access-list 2 permit ^300
