I do a trace route to an address on a switch called S1
From R1 the traceroute shows R2 - R3 - S1 (works)
From R2 the traceroute shows R3 and then it gets stuck
From R3 the traceroute shows S1 (works)
Ping from R1: OK!
Ping from R2: fails
Ping from R3: OK!
I'm a networking newbie and I don't understand how a traceroute that goes thru R2 works but if initiated from R2 it doesn't work.
What could account for that behavior?
