Question
a.
By progressively querying routers about the next router on the path to B using ICMP packets, starting with the first router
b.
By requiring each router to append the address to the ICMP packet as it is forwarded to B. The list of all routers en-route to B is returned by B in an ICMP reply packet
c.
