Link Load Balancing
Configuring Inbound Link Load Balancing
In this process, you will be need to specify a Fully Qualified Domain Name (FQDN) that is
associated with an ILLB group, and a set of link/IP pairs. The load balancer will, based on the
policy in effect (e.g., round robin) and link state, select the appropriate link to use, and return the
associated IP address. This IP address may be that of a server or a cluster (or anything else). You
must always specify in the configuration that IP which is publicly accessible (e.g., NAT address).
If the ILLB group represents a cluster, in order to have a cluster “presence” on multiple subnets,
you must create “copies” of a single cluster such that one exists on each LLB link subnet. The only
difference among the clusters will be the IP address. This creates, in effect, a “cluster of
clusters”. This “cluster of clusters” will be bound together with the ILLB group object.
Configuration of OLLB consists of the following:
1. Adding VLANs with subnets
2. Configuring gateways
3. Configuring ILLB groups
4. Add Targets to the ILLB groups
