What source IP address does a router use by default when the traceroute command is issued?
- the highest configured IP address on the router
- a loopback IP address
- the IP address of the outbound interface
- the lowest configured IP address on the router
Explanation:When sending an echo request message, a router will use the IP address of the exit interface as the source IP address. This default behavior can be changed by using an extended ping and specifying a specific source IP address.
