Study the configuration presented in the exhibit carefully.
What is the objective of the route map named test?
A.
marks all prefixes received from the 10.1.1.1 neighbor with a MED of 200
B.
marks the 10.0.0.0/8 prefix received from the 10.1.1.1 neighbor with a MED of 200
C.
marks the 10.0.0.0/8 prefix advertised to the 10.1.1.1 neighbor with a MED of 200
D.
marks all prefixes advertised to the 10.1.1.1 neighbor with a MED of 200
Explanation:
The Multiple-exit-discriminator (MED) attribute is an optional nontransitive attribute, type code 4.
MED informs external neighbors about the preferred path into an AS that has multiple entry points.A lower MED is preferred over a higher MED.
Unlike Local Preference, the MED attribute is exchanged between autonomous systems, but a
MED attribute that comes into an AS does not leave the AS. When an update enters the AS with a
certain MED value, that value is used for decision making within the AS. When BGP forwards the
routing update to another AS, the MED is reset to zero. This is true unless the outgoing MED is set
to a specific value.
Example:
RTB(config)#route-map setmedout permit 10RTB(config-route-map)#set metric
50RTB(config)#router bgp 400
