Examine the above configuration. What does the route map named test accomplish?

A.
permits only the 10.0.0.0/8 prefix to be advertised to the 10.1.1.1 neighbor

B.
marks all prefixes 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.
permits only the 10.0.0.0/8 prefix to be received from the 10.1.1.1 neighbor

E.
marks all prefixes advertised to the 10.1.1.1 neighbor with a MED of 200

F.
marks the 10.0.0.0/8 prefix received from 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 10
RTB(config-route-map)#set metric 50
RTB(config)#router bgp 400
