Route attributes are a novel aspect of BGP. With interior gateway protocols like OSPF and EIGRP, administrative distance is applied as being a tiebreaker when two routes to the same desired destination experienced distinctive future-hop IP addresses but precisely the same prefix duration.

The weight attribute is critical only to the router on which it really is adjusted. When you established a greater pounds for a selected route so that you can give it choice (an increased body weight is most popular more than a lessen a person), that bodyweight is not really marketed to other routers.
BGP makes use of classes for example “transitive”, “non-transitive”, “required”, and “optional” to classify attributes. Since fat is often a domestically important Cisco-proprietary attribute, it doesn't all into any of such groups.
The load could be adjusted on a single route by way of a route-map, or it could be established for a unique bodyweight for all routes gained from the specified neighbor. To change the pounds for all incoming routes, make use of the “weight” choice with the neighbor command soon after forming the BGP peer relationships.
R2(config)#router bgp one hundred
R2(config-router)#neighbor a hundred.1.1.1 distant-as ten
R2(config-router)#neighbor 100.1.1.1 pounds two hundred
Learning all 토토사이트 the BGP characteristics, along with when to make use of them, can seem to be an amazing task any time you first start out researching for your BSCI and CCNP tests.
