6.12.12 Configuring BGP Weights
An administrative weight is a number that you can assign to a path so that you can control the path
select ion process. The administrative weight is local to the router. A weight can be a number from 0 to
65535. Paths that the local software originates have weight 32768 by default; other paths have weight 0.
Administrator can implement routing policy through changing administrative weights.
Perform the following task in router configuration mode to configure BGP administrative weights:
neighbor {ip-address | peer-group-name} weight
weight

6.12.13 Configure the BGP Route Filtering based on Neighbor
D-Link BGP implementation can specify the BGP routes with four kinks of filtering:
Use the global configuration command ip aspath-list and neighbor filter-list command together to
apply the Aspath list filter.
ip aspath-list aspaths-list-name { permit | deny}
as-regular-expression
router bgp autonomous-system
neighbor {ip-address | peer-group-name} filter-list
aspath-list-name {in | out }
Step1：
input ip Command，prompt is as below:
(00)access-list
(01)as-path
(02)community-list
.......
Please Input the code of command to be excute(0-20): 1
input 1，Select as-path option ，prompt is as below:
(00)access-list
Please Input the code of command to be excute(0-0): 0
input 0，Select access-list option ，prompt is as below:
Command
