Kireeti et al. -
>From draft-ietf-mpls-lsp-hierarchy-03.txt authored by Kireeti:
An LSR, when performing path computation, uses not just conventional
links, but forwarding adjacencies as well. Once a path is computed,
the LSR uses RSVP/CR-LDP for establishing label binding along the
path.
However, from the JUNOS 4.4 documentation
(http://www.juniper.net/techpubs/software/junos44/swconfig44-
mpls-apps/download/swconfig44-mpls-apps.pdf):
RSVP packets automatically avoid all MPLS LSPs, including those
established by RSVP or LDP. This prevents placing one RSVP session
into another LSP, or in other words, nesting one LSP into another.
Therefore, I assume Kireeti's draft has not been implemented within Junos
(yet). Can someone tell me why Junos 4.4 has this limitation while it is
clear the issue has been thought through from a draft point of view. Was
there a technical limitation? If so, what?
Your assistance is appreciated.
