Which BGP path attribute is only used within the local router and NOT shared between all the BGP routers within the AS?
A.
MED
B.
Origin
C.
Weight
D.
Local Preference
Explanation:
The weight value is local to one router. It is not shared between routers. If one ISP connection terminates in one of the customer routers, and the other ISP connection terminate in another, the two customer routers must agree on which link to use. Using local-preference instead of wight can do this.
