Hi Ben,

   Thanks for the comments!
   The multipath feature can separete traffics to multi-gateways. If you
get two gateway routers and both of them pin on chassis. (gateway1 pin on
chassis-A, gateway2 pin on chassis-B) The multipath can seperate traffic to
those chassis automaticly.
   Otherwise, user should config many static routes to make it.

   The problem you mentioned about CMS part has not previously considered.
