Configuring inbound link load balancing
Perform the tasks in Table 8 to configure inbound link load balancing.
Table 8 Inbound link load balancing configuration task list
Task Remarks
Creating a Physical Link
Required
Allows you to create a physical link (a link where packets are forwarded), and
configure physical link parameters.
By default, no physical link exists in the system.
Configuring the Best
Performing Link Function
Optional
Allows you to configure dynamic best performing link parameters and static
best performing link entries.
For inbound link load balancing, the best performing link function allows you
to use the IP address of the DNS entry to which the corresponding physical link
belongs (domain name matching) as the DNS resolution result. If no matched
entry is found, best performing link detection is performed, that is, the device
selects the best link to the destination segment from among multiple links
according to the network delay, router hops, bandwidth, cost and weight of
the links, and generates a dynamic best performing link entry for DNS
resolution, where:
• Network delay and router hops are obtained through health monitoring.
• Bandwidth is the available bandwidth of the links.
• Cost is specified in the configuration of the physical links.
You can also manually add a static best performing link entry, which is of a
higher priority than a dynamic best performing link entry.
By default, each dynamic best performing link entry has its default value, and
there is no static best performing link entry in the system.
Configuring DNS Redirection
and DNS TTL
Required
Inbound link load balancing takes effect only after DNS redirection is enabled.
By default, DNS redirection is disabled.
Configuring a DNS Entry
Required
By default, no DNS entries exist in the system.
Setting Health Monitoring
Parameters
Optional
Configuring Global Parameters
Select High Reliability > Load Balance > Global Setting from the navigation tree to enter the
page as shown in
