IPLB is a feature which allows to distribute traffic toward internet or VPN between two or more IP resources. Two methods are allowed:

21.5.1. D IPLB

Use the command d iplb to display the IP load balancing table.

------------------------------------------------------------------------------

Meaning of the most important parameters:

ID

IP Load Balancing entry identifier [1..96].

RULE

Ip resources scanning rule [RR: Round Robin, WQ: Weighted Queue].

RES1..RES8

Ip resources in the group [# or NONE, Ip-nnn], where 'nnn' is an IP resource index [1..250].

GW1..GW8

Gateway IP address [#, 1-126.x.x.x, 127.0.0.1, 128-223.x.x.x].

21.5.2. A IPLB

This command allows to add an entry into the IPLB table.

[Caution]Caution

Changes made on the IP Load Balancing table are NOT immediately active, they can be activated by executing the initialization command init iplb. Then, remember to save the configuration (save conf).

A routing which uses an IPLB indicates this condition by showing the IPLB in the “GW: or IPLB:” field of the D IPR output.
