Configuration Procedure - HP FlexNetwork HSR6600 Configuration Manual

The second method distributes traffic of a single VPN to multiple tunnels. The transmission delays on
different tunnels can vary by a large amount. Therefore, the destination device or the upper layer
application might take a great time to sequence the packets. As a best practice, do not use the
second method.
