Just wish to ask the below.
1. If i do a traceroute from a workstation directly connected to a router, to a destination that goes through the tunnel interface L0 of that same router, will the tunnel interface IP show on the traceroute results?
2. If the destination workstation is directly connected to another router where the tunnel terminates, will the tunnel endpoint IP appear in the traceroute results?
it's even a little more complicated.
The tunnel endpoint IP address should be visible twice in the traceroute output.
