Once you’re researching for the CCNP certification, Specifically the BSCI Examination, you have to gain a good idea of BGP. BGP isn’t only one of the biggest subject areas about the BSCI exam, it’s one among the largest. BGP has an excellent a lot of information that must be mastered for BSCI success, and people of you with one particular eye to the CCIE have to understand the basics of BGP now in an effort to Develop on Those people fundamentals at a later time.
Route characteristics are a singular feature of BGP. With inside gateway protocols including OSPF and EIGRP, administrative distance is used being a tiebreaker when two routes to the exact same spot had distinctive following-hop IP addresses but the identical prefix length. BGP uses route attributes to help make this choice.
The initial attribute regarded as by BGP is fat. Excess weight can be a Cisco-proprietary BGP attribute, so for those who’re Doing the job in a very multivendor surroundings it is best to do the job with Yet another attribute to impact path collection.
The burden attribute is important only for the router on which it is actually altered. Should you set a greater excess weight for a certain route so as to give it desire (a higher bodyweight is desired in excess of a lessen a single), that excess weight just isn't marketed to other routers.
BGP takes advantage of groups such as “transitive”, “non-transitive”, “necessary”, and “optional” to classify attributes. Given that excess weight is a domestically important Cisco-proprietary attribute, it does not all into any of those groups.
The weight might be modified on just one route by means of a route-map, or it could be set for another excess weight for all routes gained from the specified neighbor. To alter the excess weight for all incoming routes, use the “weight” option While using the neighbor command soon after forming the BGP peer interactions.
R2(config)#router bgp 100
R2(config-router)#neighbor a hundred.one.1.1 distant-as 10
R2(config-router)#neighbor 100.1.one.1 fat two hundred
Finding out all of the BGP characteristics, in addition to when to make use of them, can appear to be an awesome activity if you initially get started learning on your BSCI and CCNP tests. Break this task 먹튀 down into compact sections, understand just one attribute at any given time, and soon you’ll hold the BGP characteristics mastered.
