Route characteristics are a unique element of BGP. With interior gateway protocols for example OSPF and EIGRP, administrative length is applied like a tiebreaker when two routes to precisely the same spot experienced different future-hop IP addresses but the exact same prefix duration. BGP takes advantage of route attributes to produce this alternative.
The primary attribute viewed as by BGP is pounds. Excess weight is actually a Cisco-proprietary BGP attribute, so when you’re Functioning in a very multivendor ecosystem it is best to operate with A different attribute to impact route variety.
The load attribute is critical only on the router on which it really is transformed. In the event you established the next fat for a particular route in order to give it choice (a higher excess weight is desired in excess of a decreased one), that pounds is not really marketed to other routers.
BGP utilizes classes for instance “transitive”, “non-transitive”, “required”, and “optional” to classify attributes. Considering the fact that bodyweight is often a locally significant Cisco-proprietary attribute, it does not all into any of these classes.
The load can be changed on only one route by using a route-map, or it may be established for another bodyweight for all routes received from a given neighbor. To change the bodyweight for all incoming routes, make use of the “excess weight” solution Along with the neighbor command after forming the BGP peer associations.
R2(config)#router bgp one hundred
R2(config-router)#neighbor 100.1.one.1 remote-as 10
R2(config-router)#neighbor one hundred.1.one.1 weight 200
