Configuring N + 1 Failover with 3 Load Balancers (CLI)
In this configuration, three Equalizers (Eq-A, Eq-B, and Eq-C) cooperate to provide high
availability. They do not need to be the same models. They are configured with:
l
2 VLAN subnets
l
2 clusters -- 1 preferred on each of Eq-A and Eq-B, no clusters on Eq-C
l
2 failover groups
1. Do the following on all three Load Balancers:
a. Create all VLANs and subnets necessary for your configuration (see
on page 297). For this example, we assume two VLANs:
vlan2
with two
and
vlan3
) with one or two subnets each (
172net
and
192net
, respectively), and
that these are cable-connected to the load balancer through separate front-
panel ports. As with any failover configuration, the VLAN/subnet configuration
on all peers must be exactly the same, except for object names and tagged/un-
tagged port assignments.
b. Set the Failover (or Virtual) IP address on each VLAN subnet, as in these
examples:
eqcli >
vlan vlan2 subnet 172net virt_addr 172.16.0.169
eqcli >
vlan vlan3 subnet 192net virt_addr 192.168.0.169
c. Set the command and heartbeat flags on the subnets. One subnet must have the
command flag enabled, both subnets need the heartbeat flag since we want to
fail over when there is a connectivity issue on any subnet:
eqcli >
vlan vlan2 subnet 172net flags command,heartbeat
eqcli >
vlan vlan3 subnet 192net flags heartbeat
d. Change the system
hostname
so it is unique.This is useful when examining
logs:
eqcli >
hostname
name
