ok folks a quick update to say it was fixed by running a 
 
process restart rib
process restart lm
 
This restarts the rib and lable-mapper in the box - worked like a charm.
Seemed that the SE-800 was stuck in flux on the label distribution.

Hello Sridhar, 

The SeOs version on London is SEOS-2.6.3.2-Release and Paris is
SEOS-2.6.5.3-Release. One of my colleaguges has raised a case with TAC to
see if they can help :)

Umar.

hi Umar, 
what versions of SEOS are you running on the two boxes? 

besides the ping of rsvp lsp LONDON-PARIS which fails, is there some other
problem that you see? 

thanks
