Which statement is true about IBGP routers? Select the best response.

A.
They must be fully meshed.

B.
They can be in a different AS.

C.
They must be directly connected.

D.
They do not need to be directly connected.

Explanation:
When two routers establish a TCP enabled BGP connection, they are called neighbors or peers. Each router
running BGP is called a BGP speaker. Peer routers exchange multiple messages to open and confirm the
connection parameters, such as the version of BGP to be used. If there are any disagreements between the
peers, notification errors are sent and the connection fails. To be a neighbor of BGP no need to be directly
connected.
