Internet or large enterprise environments using routers

You can use HP APA link aggregation successfully in certain environments employing routers.
You must be careful because a particular router might not have a load balancing capability.
Additionally, switches employed between the server employing HP APA and the router inject
another level of complexity that you must analyze before determining that the environment is
a candidate for HP APA link aggregations.
Figure 3-2 (page 23)
configuration makes the following assumptions:
• The router or switching router connected to the server provides trunking or load balancing
using an IP address-based load-balancing algorithm.
• There will be many TCP/UDP client connections. The HP APA IP address load-balancing
algorithm provides effective outbound network traffic load balancing, as does the TCP/UDP
port address algorithm. Do not use the MAC address algorithm because all packets
transmitted from the server would contain the same source and destination MAC addresses.
