DDTS CSCsh56847 requests to bump up the limit. I guess for now you might
be able to do "ip rsvp bandwidth" without an argument to have the router
allocate 75% of the available BW dynamically. Haven't tried this on a
10GE channel though.

TE over a channel is a challenge anyway as RSVP doesn't take the actual
load-sharing into account.. I.e. RSVP might allow two 8G reservations
which end up being hashed over the same physical port, resulting in
packet loss..
