Configuring BGP Weights

Perform this task to assign a weight to routes received from a neighbor. A weight is a number that you can
assign to a path so that you can control the best-path selection process. If you have particular neighbors that
you want to prefer for most of your traffic, you can use the weight command to assign a higher weight to all
routes learned from that neighbor.
Before You Begin
Note The clear bgp command must be used for the newly configured weight to take effect.
