After you’re learning to the CCNP certification, Specially the BSCI Test, it's essential to acquire a good understanding of BGP. BGP isn’t just one of the most important subjects to the BSCI Test, it’s one of the biggest. BGP has an excellent quite a few specifics that should be mastered for BSCI good results, and those of you with 1 eye over the CCIE will have to find out the fundamentals of BGP now in an effort to Develop on those fundamentals at a later time.
Path attributes are a unique feature of BGP. With interior gateway protocols for instance OSPF and EIGRP, administrative distance is applied as being a tiebreaker when two routes to a similar spot experienced distinct subsequent-hop IP addresses but a similar prefix length. BGP takes advantage of route characteristics to make this option.
The primary attribute viewed as by BGP is bodyweight. Weight can be a Cisco-proprietary BGP attribute, so when you’re Functioning in the multivendor natural environment you must work with A different attribute to affect path collection.
The load attribute is critical only towards the router on which it really is modified. In case you set an increased pounds for a certain route as a way to give it choice (an increased pounds is chosen in excess of a decrease 1), that weight is just not advertised to other routers.
BGP works by using categories for instance “transitive”, “non-transitive”, “mandatory”, and “optional” to classify attributes. Since fat is really a regionally sizeable Cisco-proprietary attribute, it does not all into any of such categories.
The load can be modified on just one route 토토 by means of a route-map, or it could be established for a special fat for all routes acquired from a given neighbor. To alter the body weight for all incoming routes, use the “pounds” alternative With all the neighbor command right after forming the BGP peer interactions.
R2(config)#router bgp one hundred
R2(config-router)#neighbor a hundred.one.1.1 remote-as ten
R2(config-router)#neighbor one hundred.1.1.one bodyweight two hundred
Finding out each of the BGP characteristics, in addition to when to utilize them, can seem to be an awesome endeavor after you initial start off finding out for your personal BSCI and CCNP exams. Split this process down into little parts, find out just one attribute at a time, and soon you’ll provide the BGP attributes mastered.
