Wouldn't you just do that in your reporting? The report engine usually
has options for interface, ingress/egress, prefix range, protocol, ....
Then when you need to aggregate for a specific interface for additional
troubleshooting, you have all the information for when you need it.
Yes, your aggregate numbers for total packets transiting is double, but
I generally have specific reports for specific traffic patterns I focus
on anyway.
