Path characteristics are a novel element of BGP.

BGP works by using path attributes for making this selection.
The very first attribute regarded as by BGP is pounds. Excess weight is usually a Cisco-proprietary BGP attribute, so for those who’re Doing work inside of a multivendor ecosystem you should perform with One more attribute to influence path range.
The burden attribute is important only towards the router on which it is actually modified. If you established the next weight for a specific route in an effort to give it preference (an increased fat is favored more than a lessen 1), that bodyweight is not marketed to other routers.
BGP works by using groups which 먹튀검증 include “transitive”, “non-transitive”, “obligatory”, and “optional” to classify attributes. Since pounds is often a domestically important Cisco-proprietary attribute, it doesn't all into any of these groups.

To alter the bodyweight for all incoming routes, make use of the “pounds” selection With all the neighbor command soon after forming the BGP peer relationships.
R2(config)#router bgp 100
R2(config-router)#neighbor 100.one.1.1 remote-as 10
R2(config-router)#neighbor one hundred.1.1.one pounds 200
Studying most of the BGP characteristics, as well as when to rely on them, can feel an overwhelming activity once you to start with start out learning for your personal BSCI and CCNP examinations.
