If you’re finding out for that CCNP certification, especially the BSCI Test, you need to achieve a sound understanding of BGP. BGP isn’t only one of the greatest matters over the BSCI exam, it’s one among the biggest. BGP has a fantastic a lot of information that has to be mastered for BSCI good results, and people of you with a person eye within the CCIE must master the basics of BGP now as a way to Construct on those fundamentals at a later on time.
Route attributes are a singular characteristic of BGP. With interior gateway protocols such as OSPF and EIGRP, administrative length is used to be a tiebreaker when two routes to the same desired destination had distinctive next-hop IP addresses but precisely the same prefix duration. BGP takes advantage of path attributes to make this choice.
The initial attribute considered by BGP is fat. Body weight is really a Cisco-proprietary BGP attribute, so for those who’re Performing in the multivendor environment you'll want to work with Yet another attribute to impact route range.
The load attribute is significant only towards the router on which it's transformed. Should you established a greater pounds 먹튀검증 for a selected route as a way to give it desire (a greater pounds is chosen above a lessen 1), that bodyweight just isn't marketed to other routers.
BGP uses groups which include “transitive”, “non-transitive”, “mandatory”, and “optional” to classify attributes. Considering that body weight is a domestically major Cisco-proprietary attribute, it doesn't all into any of those groups.
The load is usually improved on only one route by way of a route-map, or it could be established for a unique fat for all routes received from the given neighbor. To change the fat for all incoming routes, make use of the “fat” option Using the neighbor command soon after forming the BGP peer relationships.
R2(config)#router bgp 100
R2(config-router)#neighbor one hundred.1.1.1 remote-as ten
R2(config-router)#neighbor a hundred.1.1.1 bodyweight two hundred
Finding out every one of the BGP characteristics, along with when to use them, can appear to be an amazing process when you very first start off researching for your BSCI and CCNP tests. Crack this job down into tiny sections, understand a single attribute at a time, and shortly you’ll contain the BGP attributes mastered.
