Any time you’re researching to the CCNP certification, Specifically the BSCI Examination, you will need to acquire a stable understanding of BGP. BGP isn’t just one of the most important subjects on the BSCI Test, it’s certainly one of the largest. BGP has a great a lot of details that need to be mastered for BSCI success, and people of you with 1 eye over the 토토 CCIE need to understand the fundamentals of BGP now so as to Develop on All those fundamentals at a later time.
Route characteristics are a unique feature of BGP. With inside gateway protocols which include OSPF and EIGRP, administrative distance is made use of to be a tiebreaker when two routes to the exact same destination had various next-hop IP addresses but the exact same prefix length. BGP makes use of route attributes to produce this decision.
The initial attribute thought of by BGP is body weight. Body weight is often a Cisco-proprietary BGP attribute, so if you’re working within a multivendor surroundings you ought to function with A different attribute to affect route variety.
The burden attribute is significant only towards the router on which it's changed. If you established a greater pounds for a selected route so as to give it preference (the next excess weight is desired more than a decrease just one), that fat isn't marketed to other routers.
BGP utilizes classes such as “transitive”, “non-transitive”, “required”, and “optional” to classify attributes. Considering that bodyweight is really a domestically important Cisco-proprietary attribute, it doesn't all into any of those classes.
The weight may be transformed on a single route by way of a route-map, or it could be established for a unique pounds for all routes been given from a specified neighbor. To change the excess weight for all incoming routes, use the “excess weight” solution with the neighbor command immediately after forming the BGP peer associations.
R2(config)#router bgp one hundred
R2(config-router)#neighbor one hundred.one.1.1 distant-as ten
R2(config-router)#neighbor one hundred.1.1.1 pounds two hundred
Finding out all of the BGP attributes, together with when to make use of them, can look an overwhelming process when you very first start off studying for your personal BSCI and CCNP exams. Split this activity down into small parts, understand a person attribute at any given time, and shortly you’ll hold the BGP characteristics mastered.
