Re: [mpls-linux-general] LDP config... confused!

[<sam...@ya...>]

Hi James,

nope... I have only ospfd running as the routing
protocol. the funny thing is that mplsd does create
the outlabels sometimes while sometimes it doesn't!
... I haven't been able to pin-point the conditions
that exist when the out-labels are getting created.
Maybe I'll go through the trace output and see if I
can figure out something.
But as far as existing route entry is concerned, I
believe it would have been created by ospfd. Is that
right? 

thanks and regards,
Sameer
