The load attribute is important only into the router 토토사이트 on which it really is adjusted. Should you established the next excess weight for a particular route to be able to give it desire (a greater bodyweight is favored above a decrease a person), that weight is not really marketed to other routers.
BGP employs classes such as “transitive”, “non-transitive”, “obligatory”, and “optional” to classify characteristics. Since bodyweight is usually a locally considerable Cisco-proprietary attribute, it does not all into any of these groups.
The load is usually improved on just one route through a route-map, or it can be established for another weight for all routes been given from a provided neighbor. To alter the fat for all incoming routes, utilize the “body weight” alternative with the neighbor command just after forming the BGP peer interactions.
R2(config)#router bgp one hundred
R2(config-router)#neighbor a hundred.1.one.one distant-as 10
R2(config-router)#neighbor 100.1.1.one pounds two hundred
