Hi Bhawna,

By default you will loadbalance the traffic among parallel tunnels with
the ratio proportional to your configured bw on the tunnels. Remember
that we use cef src/dst hash so with a little number of flows you may be
using for a test the result may not be very visible. 

The above should address your question, but just for completness you can
cfg a static route to point to a tunnel or use PBR with any acl to also
direct your incomming traffic to a tunnel. All are available, but I am
not convinced if you really will need them :).

Rgs,
