Usage
Information
Loopback interfaces are up constantly and the BGP session may need one interface constantly up to
stabilize the session. The neighbor update-source command is not necessary for directly
connected internal BGP sessions.
Neighbors are sorted according to the source and destination ip addresses. If an update-source ip address
exists, then the source ip address determines the order in which the neighbors are displayed.
neighbor weight
Assign a weight to the neighbor connection, which is used to determine the best path.
Syntax
neighbor {ip-address | peer-group-name} weight weight
To remove a weight value, use the no neighbor {ip-address | peer-group-name} weight
command.
Parameters
ip-address Enter the IP address of the peer router in dotted decimal format.
peer-group-name Enter the name of the peer group to disable all routers within the peer group.
weight Enter a number as the weight. The range is from 0 to 65535. The default is 0.
Defaults 0

preferred.

value is preferred.
If you configure the set weight command in a route map applied to this neighbor, the weight set in
that command overrides the weight set in the neighbor weight command.
