Na kratko ne moje da stane.
Tova koeto stava e:
UDP sys SRCIP-TR ot traceroute hosta do DSTIP niakoia ot 3-te mreji.
za koeto se generira ICMP paket sys SRCIP=0.0.0.0 do SRCIP-TR (DSTIP go ima vytre v paketa no se gubi kato info za routinga)
sled koeto SRCIP koeto e 0 se populva ot routinga -> v main table default e prez 193.68.0.195 za koeto source e 193.68.0.202
i za tova vinagi otgovaria s nego, t.e. tozi router izliza po default s tozi address i za tova otgovaria s nego pri traceroute.
