Once you’re learning for the CCNP certification, Particularly the BSCI Test, you will need to acquire a solid comprehension of BGP. BGP isn’t only one of 토토 the most significant subject areas over the BSCI Test, it’s among the biggest. BGP has a great quite a few specifics that need to be mastered for BSCI achievement, and people of you with a person eye within the CCIE should master the fundamentals of BGP now so as to Establish on All those fundamentals at a later time.
Path characteristics are a singular attribute of BGP. With interior gateway protocols such as OSPF and EIGRP, administrative length is applied to be a tiebreaker when two routes to precisely the same destination experienced diverse subsequent-hop IP addresses but the exact same prefix duration. BGP uses route characteristics to help make this option.
The very first attribute regarded by BGP is body weight. Fat is often a Cisco-proprietary BGP attribute, so for those who’re Doing the job in a very multivendor setting you should do the job with Yet another attribute to impact path selection.
The load attribute is critical only for the router on which it is improved. In case you established a better fat for a particular route so that you can give it preference (a greater excess weight is most well-liked around a decreased one particular), that body weight is not advertised to other routers.
BGP employs types for example “transitive”, “non-transitive”, “mandatory”, and “optional” to classify characteristics. Since bodyweight can be a locally significant Cisco-proprietary attribute, it doesn't all into any of such groups.
The load may be transformed on only one route via a route-map, or it could be established for a different excess weight for all routes obtained from the specified neighbor. To alter the fat for all incoming routes, utilize the “excess weight” choice While using the neighbor command following forming the BGP peer relationships.
R2(config)#router bgp a hundred
R2(config-router)#neighbor a hundred.one.one.1 distant-as ten
R2(config-router)#neighbor 100.1.one.1 bodyweight 200
Finding out most of the BGP attributes, along with when to rely on them, can seem to be an overwhelming process whenever you very first start off researching for your BSCI and CCNP exams. Split this process down into tiny sections, discover a single attribute at any given time, and shortly you’ll provide the BGP attributes mastered.
