IPLB is a feature which allows to distribute traffic toward internet or VPN between two or more IP resources. Two methods are allowed:
RR: Round Robin. The packets are sequentially
sent through the IP resources of the group.
WQ: Weighted Queue. The IP resource of the
group with the shorter transmission queue of the same priority is used
for the transmission of the packet under processing, otherwise packets
are sent sequentially on the resources of the group.
Use the command d iplb to display the IP load balancing table.

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.
