Which of these best identifies the types of prefixes a router running BGP will advertise to an EBGP
peer?

A.
prefixes received from any other BGP peer and prefixes locally originated via network
statements or redistributed to BGP

B.
all prefixes in its IP routing table.

C.
only prefixes received from EBGP peers and prefixes locally originated via network statements
or redistributed.

D.
only prefixes received from EBGP peers and prefixes received from route reflectors.

E.
all prefixes in its routing table except the prefixes received from other EBGP peers.

F.
all prefixes in its routing table except the prefixes received from other IBGP peers.

Explanation:

eBGP peers will advertise all known eBGP routes to all other eBGP peers.
iBGP peers will only advertise their own internal routes to other iBGP peers.
A BGP speaking router will never advertise another iBGP peer’s routes to any other iBGP peer.
