Cisco NCS 5500 Series

Example:
RP/0/RP0/CPU0:router(config-bgp)# default metric 10
Sets the default metric, which is used to set the MED to advertise to peers for routes that do not already have a metric
set (routes that were received with no MED attribute).

Configure BGP Weights
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. Perform this task to assign a weight to routes
received from a neighbor.

DETAILED STEPS
Step 1
configure
Step 2
router bgp as-number
Example:
RP/0/RP0/CPU0:router(config)# router bgp 120
Specifies the autonomous system number and enters the BGP configuration mode, allowing you to configure the BGP
routing process.
Step 3
neighbor ip-address
Example:
RP/0/RP0/CPU0:router(config-bgp)# neighbor 172.168.40.24
Places the router in neighbor configuration mode for BGP routing and configures the neighbor IP address as a BGP peer.
