II. tracert
Use the
tracert
command to trace the gateways through which a packet passes from
source to destination for network connectivity test and fault location.
The following is how
a
tracert
command operates:
1)
Tracert sends a packet with TTL value of 1.
2)
The fist hop sends back an ICMP TTL Expired message.
3)
Tracert resends the packet with TTL value of 2.
4) The second hop sends back an ICMP TTL Expired message when the packet
arrives.
This process continues till the packet reaches its destination. The route is determined
by examining the ICMP Time Exceeded messages sent back by intermediate routers.
Perform the following configuration in any view.
