Hi,
I have a comment regarding the mplsTunnelMaxHops scalar that indicates the
maximum number of hops that can be specified on each tunnel supported by the
LSR.
This scalar is a read only attribute but I can find it very useful to let
configure it as well. 
One of the CSPF constraints is the maximum number of hops the LSP may follow
through. The limitation on the maximum number for example can result from
the maximum packet size when fragmentation is not supported. In such a case
the maximum number of hops can depend on the network nature
(numbered/unnumbered). Instead of hard coding it with the worst case number,
let the network administrator, that is aware  of the network nature,
configure it.
Thanks, Nurit.
