An EBGP session sources its TCP connection from which IP address?
A . The IP address of the primary address assigned to the loopback interface.
B . The IP address assigned as the router I
D . The IP address of the preferred address assigned to the loopback interface.
E . The IP address of the interface that connects the two BGP speakers.
Answer: D
Explanation:
The BGP session between two BGP peers is said to be an external BGP (eBGP) session if the BGP peers are in different autonomous systems (AS). A BGP session between two BGP peers is said to be an internal BGP (iBGP) session if the BGP peers are in the same autonomous systems. By default, the peer relationship is established using the IP address of the interface closest to the peer router.
