Disable RSVP local revertive mode—Configure the
the
[edit protocols rsvp]
revertive mode as specified in RFC 4090, Fast Reroute Extensions to RSVP-TE for LSP).
RSVP local revertive mode is supported on all Juniper Networks routers running the
Junos OS software by default. If you configure the
Juniper Networks router uses global revertive mode instead. You might need to disable
RSVP local revertive mode on Juniper Networks routers if your network includes
equipment that does not support this mode.

Shortest Path First (CSPF) messages. You can now see the reason(s) for the CSPF
path computation and rejection. The following list shows some of the enhanced CSPF
messages (depending on your network configuration, the type of messages you see
might be different):

Enhancement to CSPF traceoptions—In Junos OS Release 10.3 and later, the
Constrained Shortest Path First (CSPF) trace messages have been updated to provide
more detailed information about CSPF path computation and rejection. You configure
the CSPF traceoptions by including the
hierarchy level. The following list shows some of the enhanced CSPF trace
