[LUGOS] Re: [LUGOS-BLA] ping question...

[Damir Horvat]

ZIvjo!

www.ietf.org/rfc/rfc792.txt:

"ICMP, uses the basic support of IP as if it were a higher
   level protocol, however, ICMP is actually an integral part of IP, and
   must be implemented by every IP module."

TCP/IP Illustrated Vol. 1 - W. Richard Stevens:
	stran 2, figure 1.1 - network layer: IP, ICMP, IGMP


ok, ping ni tema predavanja, to je icmp. In jaz bom povedal, da je ICMP
layer 2 protokol (network layer). Ce se pa kdo ne strinja, oz. me preprica
drugace, pa prosim.

lp,
damir
