Hi Eric,

Thank you very much for your interest. But I've configured yet my scenario
and I see with the 'show mpls traffic-eng tunnel' that the configuration is
up in all routers of the path. However, when I send traffic to the network
through the tunnel with bandwidth reservation, it acts as if the reservation
does not exist, and drives me to conclude that the reservations are not well
implemented.
It can be a bug of this version !?, I don't know.


Best regards.

Carlos Parada
