Any time you’re finding out to the CCNP certification, Primarily the BSCI Test, you must attain a strong comprehension of BGP. BGP isn’t just one of the greatest matters within the BSCI Test, it’s one of the most important. BGP has a terrific lots of facts that have to be mastered for BSCI good results, and people of you with one eye about the CCIE have to discover the basics of BGP now to be able to Develop on People fundamentals at a later on time.
Route characteristics are a unique element of BGP. With inside gateway protocols for example OSPF and EIGRP, administrative distance is made use of for a tiebreaker when two routes to a similar destination had distinct following-hop IP addresses but the identical prefix size. BGP works by using path attributes to make this alternative.
The very first attribute regarded as by BGP is weight. Fat is usually a Cisco-proprietary BGP attribute, so should you’re Doing work inside a multivendor setting you should work with A different attribute to influence route range.
The burden attribute is important only to the router on which it is actually adjusted. For those who established a greater fat for a selected route to be able to give it desire (the next bodyweight is chosen over a reduce 1), that fat just isn't advertised to other routers.
BGP uses categories for instance “transitive”, “non-transitive”, “necessary”, and “optional” to classify attributes. Considering that excess weight is usually a domestically important Cisco-proprietary attribute, it does not all into any of such groups.
The burden could be altered on just one route by way of a route-map, or it could be set for another bodyweight for all routes been given from the presented neighbor. To alter the pounds for all incoming routes, use the “pounds” solution Together with the neighbor command right after forming the BGP peer associations.
R2(config)#router bgp one hundred
R2(config-router)#neighbor one hundred.1.1.one remote-as 10
R2(config-router)#neighbor one hundred.1.one.1 pounds 200
Understanding every one of the BGP attributes, together with when to use them, can feel an amazing task if you 1st begin researching in your BSCI and CCNP tests. Split this job down into compact components, master a person attribute at a time, and 먹튀 soon you’ll have the BGP attributes mastered.
