If you’re studying to the CCNP certification, Specifically the BSCI Test, it's essential to get a solid idea of BGP. BGP isn’t only one of the largest topics about the BSCI Examination, it’s considered one of the most important. BGP has a great numerous information that must be mastered for BSCI results, and those of you with just one eye within the CCIE should understand the fundamentals of BGP now in an effort to Create on those fundamentals in a later on time.
Path characteristics are a singular feature of BGP. With interior gateway protocols for instance OSPF and EIGRP, administrative length is used as being a tiebreaker when two routes to the exact same spot had distinctive up coming-hop IP addresses but the same prefix size. BGP uses path characteristics to make this selection.
The 1st attribute regarded by BGP is bodyweight. Excess weight is a Cisco-proprietary BGP attribute, so if you’re Operating inside of a multivendor environment you must get the job done with Yet another attribute to impact path range.
The weight attribute is critical only to your router on which it really is transformed. Should you established the next fat for a specific route in an effort to give it desire (a better fat is desired over a reduced one particular), that weight isn't advertised to other routers.
BGP uses types such as “transitive”, “non-transitive”, “obligatory”, and “optional” to classify characteristics. Because excess weight is really http://edition.cnn.com/search/?text=토토사이트 a domestically 토토 significant Cisco-proprietary attribute, it does not all into any of these categories.
The load could be adjusted on a single route through a route-map, or it might be set for a distinct body weight for all routes gained from a offered neighbor. To alter the excess weight for all incoming routes, make use of the “bodyweight” alternative Along with the neighbor command soon after forming the BGP peer interactions.
R2(config)#router bgp a hundred
R2(config-router)#neighbor 100.one.one.one distant-as 10
R2(config-router)#neighbor one hundred.one.one.1 bodyweight 200
Studying all the BGP attributes, in addition to when to use them, can seem an overwhelming task once you initial start finding out to your BSCI and CCNP tests. Crack this process down into smaller components, discover one particular attribute at a time, and soon you’ll hold the BGP characteristics mastered.
