Path attributes are a singular element of BGP. With inside gateway protocols including OSPF and EIGRP, administrative distance is made use of as a tiebreaker when two routes to the exact same destination experienced unique upcoming-hop IP addresses but precisely the same prefix length. BGP works by using path characteristics to produce this alternative.
The 1st attribute regarded by BGP is weight. Body weight is often a Cisco-proprietary BGP attribute, so in case you’re working inside a multivendor surroundings you should work with another attribute to affect path collection.
The weight 토토사이트 attribute is significant only to your router on which it's adjusted. When you established a higher weight for a certain route as a way to give it desire (a higher fat is favored around a reduced a single), that fat is just not marketed to other routers.
BGP employs types like “transitive”, “non-transitive”, “required”, and “optional” to classify attributes. Considering that body weight can be a domestically considerable Cisco-proprietary attribute, it does not all into any of such types.
The burden is often modified on an individual route by means of a route-map, or it can be established for a distinct pounds for all routes received from a supplied neighbor. To alter the body weight for all incoming routes, use the “weight” selection Along with the neighbor command just after forming the BGP peer associations.
R2(config)#router bgp a hundred
R2(config-router)#neighbor one hundred.1.one.1 distant-as 10
R2(config-router)#neighbor 100.one.1.1 weight 200
