From your initial e-mail I could tell you were trying to do,
in IOS, what JunOS does, i.e., treat LDP and RSVP as route
sources and install forwarding entries into the routing
table with preferences (administrative distance in IOS),
e.g.,:
[edit]
[EMAIL PROTECTED] run show route table mpls
mpls.0: 70 destinations, 70 routes (70 active, 0 holddown, 0
hidden)
Restart Complete
+ = Active Route, - = Last Active, * = Both
0 *[MPLS/0] 2d 07:17:30, metric 1
Receive
1 *[MPLS/0] 2d 07:17:30, metric 1
Receive
2 *[MPLS/0] 2d 07:17:30, metric 1

299776 *[LDP/9] 09:32:41, metric 1

I haven't had to treat them as routing protocols in JunOS,
and just use them for what they are intended - life is
simpler.
Aside from what others have already mentioned in this
thread, I'm not sure IOS treats these label distribution
protocols as routing protocols.
Cheers,
Mark.
