Which protocol is the path-vector routing protocol and the only current Exterior Gateway Protocol (EGP)?

Explanation:
Border Gateway Protocol is the path-vector protocol used for inter-domain routing across autonomous systems. It maintains the AS_PATH for each route, which lists the sequence of autonomous systems a route traverses. This path information helps prevent loops and enables policy-based path selection between different networks, making it the current Exterior Gateway Protocol in widespread use. Other options don’t fit: BFD is a link-failure detection protocol, RIP is an interior gateway protocol that uses hop count, and IPv4 is a network-layer protocol, not a routing protocol.
