[nsp] PPP Multilink problem.

[mahesh_s]

Michael,

I agree on the input but if you look at the output

614000 + 463000 = 1077000 where as the one on multilink is 2153000, 
which is double the sum of individual interface.

What is your input on this?

It is not double the sum, it is the sum of them.  Do the math yourself.

96000 + 96000 = 192000 which is close enough to 197000 (the input rates).

Of course this is normal.  You're splitting the traffic going through the 
multilink interface into two physical interfaces.

They're not always going to totally add up, they are after all averages, 
and if one link is lossy or different delay characteristics it can have a 
different number of packets.
