Which of the following statements are true about basic BGP concepts?

The router ID of BGP is a 32-bit value used to identify a BGP device. Each BGP device must have a unique router ID. Otherwise, BGP connections cannot be established between peers.

BGP running within an AS is called IBGP. To quickly transmit routes, a BGP device advertises the routes learned from an IBGP peer to other IBGP peers.

BGP running between ASs is called EBGP. To prevent routing loops between ASs, a BGP device discards the routes received from EBGP peers if they carry the local AS number.

The device that sends BGP messages is called a BGP speaker. It receives or generates new messages and advertises them to other BGP speakers.
