Re: per-packet load sharing in cef or dcef

["Feger, James" <jfeger () feger net>]

I am not sure what is happening for you, but as a general rule of thumb I
don't run per-packet load sharing on circuits that are not 'the same'.
The need for packet re-ordering goes way up when you are running
per-packet on two types of circuit.  Are the circuits provisioned for the
same speed at least?
