Configuration Guide - SPU
The process of combined load balancing is actually the combination of firewall load balancing
and server load balancing. The combined load balancing prevents firewalls from being the
network bottleneck and improves network service performance and availability.
6.3 Configuring Egress Link Load Balancing
On the network where multiple ISP egresses exist, you can configure egress link load balancing
so that links are selected dynamically and service reliability is improved.
6.3.1 Establishing the Configuration Task
Before configuring egress link load balancing, familiarize yourself with the applicable
environment, complete the pre-configuration tasks, and obtain the required data. This helps you
complete the configuration task quickly and accurately.
Applicable Environment
On a network where an enterprise leases two or multiple ISP egresses from which enterprise
users can access the public network through the private network, you can configure egress link
load balancing. When an enterprise user accesses the external network, the SPU selects a link
according to the priorities, weights, or bandwidths of egress links. In this manner, the egress
links are properly used, the risk on the reliability caused by egress faults is prevented, and the
problem of network access caused by insufficient bandwidth is solved.
Pre-configuration Tasks
Before configuring egress link load balancing, complete the following tasks:
