Description
The traceroute command traces the route taken by a packet to reach a remote IP host. The
traceroute command examines the route taken by a packet traveling from a source to a
destination. By default, the source of the packet is the SSR. However, one can specify a
different source and track the route between it and a destination. The route is calculated
by initially sending a probe (packet) from the source to the destination with a TTL of 1.
Each intermediate router that is not able to reach the final destination directly will send
back an ICMP Time Exceeded message. Subsequent probes from the source will increase
the TTL value by 1. As each Time Exceeded message is received, the program keeps track
of the address of each intermediate gateway. The probing stops when the packet reaches
the destination or the TTL exceeds the max-ttl value.
