Route attributes are a novel function of BGP. With interior gateway protocols for instance OSPF and EIGRP, administrative distance is utilised to be a tiebreaker when two routes to the exact same desired destination had different following-hop IP addresses but the same prefix duration. BGP utilizes path attributes to create this alternative.

The burden attribute is important only to the router on which it is actually altered. Should you set a greater pounds for a selected route so that you can give it preference (the next pounds is favored more than a lower just one), that bodyweight is not really advertised to other routers.
BGP utilizes groups including “transitive”, “non-transitive”, “obligatory”, and “optional” to classify characteristics. Considering the fact that body weight is a domestically considerable Cisco-proprietary attribute, it does not all into any of those groups.
The burden is often changed on just one route via a route-map, or it may be established for a different fat for all routes been given from a specified neighbor. To alter the body weight for all incoming routes, utilize the “excess weight” solution with the neighbor command following forming the BGP peer relationships.
R2(config)#router bgp one hundred
R2(config-router)#neighbor a hundred.one.one.1 remote-as ten
R2(config-router)#neighbor 100.1.1.1 bodyweight two hundred
