Chapter 5: Initial Setup
This chapter covers the basic setup and initialization process for the Avaya VPN Gateway (AVG ). It
introduces the concept of
clusters
, and provides detailed instructions for reinstalling the VPN Gateway
software, should it become necessary.
Clusters
All VPN Gateways are members of a
cluster
. A cluster can consist of one single VPN Gateway
or a group of AVGs that share the same configuration parameters. There can be more than
one AVG cluster in the network, each with its own set of parameters and services. If the VPN
Gateway is used for SSL Acceleration, each cluster can be set up to serve different real
servers.
New and Join
Each time you perform an initial setup of an VPN Gateway and select
new
in the Setup menu, you create a new cluster which initially only has one single member. You
can add one or more VPN Gateways to any existing cluster by performing an initial setup and
select
join
in the Setup menu.
Configuration is Replicated among Master AVGs
The configuration parameters are stored in a database, which is replicated among the VPN
Gateways designated as masters in a cluster. By default, the first four VPN Gateways in a
given cluster are set up as masters. Additional AVGs are automatically set up as slaves, which
means they depend on a master AVG in the same cluster for proper configuration. However,
even if three of the masters fail, the remaining (AVGs) are still operational and can have
configuration changes made to them. Note that one master at a minimum has to be functional
to be able to make configuration changes. If all masters have failed, the slaves will still be
capable of processing SSL traffic.
