Hi,
please clear the situation:

reference:(framework for mpls, draft, page 51)
http://www.ietf.org/internet-drafts/draft-ietf-mpls-framework-05.txt

1:
Is it necessary that we MUST make level only at
IGP(OSPF etc) and BGP based?
It means that there will be ONLY two levels in each
domain???
If yes, then there will be only two labels in each
domain (at maximum) one is OSPF label and other will
be BGP label??
If there is another nested LSP (level) tunnel in
domain 2, then I think there will be three labels at
one time???

2:
framework for mpls, draft, page 51)
http://www.ietf.org/internet-drafts/draft-ietf-mpls-framework-05.txt

Because R4->R7 is a OSPF level, so R6 will be
penultimate and R7 will be the egress of that level
(tunnel), and also R7 will act as the penultimate for
the R8??? Is it true?? If YES then:
R8 will receive unlabelled packet (because R7 will act
as the penultimate for R8), and R8 will attach a new
BGP label that will be for R9 in the next domain????
Is it true???

thanks again
Tahir
