[j-nsp] BGP load balancing on 2 links (same ISP)

[Ihsan Junaidi Ibrahim]

Yes, if I remember correctly the syntax is a holdover from the ages of IP1
where per-packet load balancing behaves exactly like one. In IP2, per-packet
is flow-based.

Ihsan,
      I've heard that although the load balance option is known as
"per-packet" 
but it behaves more like "per flow". Meaning packets would not be breaked up
and merged on the other end. Am i right?
