Given the following situation:
PC --- |aa RTR1 bb| --- |aa RTR2 bb| --- |aa RTR3 bb| etc
Each of the |aa rtr bb|
is meant to be a router with two ports aa
and bb
.
When I do a trace route from my PC, which router port address should respond with time to live exceeded in transit message?
I seem to remember being taught to think of the router as being in as many parts as ports, so that in my scenario when aa
is forwarding the packet to bb
and decrements the TTL to 0, it will be the address of the aa
port in the failure message. I am trying to find the definitive answer.
