Re: path taken by a packet feedback

["Truong Dieu Linh" <truongtd@IRO.UMontreal.CA>]

 The draft that I read is at
 http://www.ietf.org/internet-drafts/draft-ietf-tewg-mib-03.txt
 dated Septembre 2002, expire March 2003. Is that the one you mentionned?.

 I have another question about tunnel. As the MIB, how many tunnel may have
between to node.
 -  If only one. In that case, sourse and destination nodes adresses re the
key attribute of teTunnelEntry, which identify the teTunnelEntry?.
 - If there are many tunnels, what are the different between tunnels. What
is the semantic indentification of this tunnel, surely that we have an
identification tunnelIndex or tunnelName but it does not signifies a
pacticular caracter of a tunnel.
