Using a DNS name to initiate a trace route
Suppose you want to trace the route from a device to a remote server identified as NYC02 on
domain newyork.com.
FIGURE 9
Because the newyork.com domain is already defined on the device, you need to enter only the host
name, NYC02, as noted below.
BigIron RX# traceroute nyc02
Syntax: traceroute <host-ip-addr> [maxttl <value>] [minttl <value>] [numeric] [timeout <value>]
The only required parameter is the IP address of the host at the other end of the route.
After you enter the command, a message indicating that the DNS query is in process and the
current gateway address (IP address of the domain name server) being queried appear on the
screen.
