Using the SSR Configuration Script
When running the SSR configuration script, option 2. Generate Cluster Definition, always generates a 16-digit random number that is saved in dbcluster.dat as the CLUSTER_DEFAULT_KEY. Upon selecting configure script option 3. Configure Cluster Node, the following occurs:
The CLUSTER_DEFAULT_KEY is used to configure spi.ini [Keys] if:
CurrentKey= has not already been configured.
The first key 1= has not already been configured.
Any IP addresses previously specified for nodes in the cluster are added to the spi.ini [Hosts] section if they are not already present.
If you are migrating from an older spi.ini, then:
It is likely that [Keys] have already been configured and it is up to you to maintain [Keys] in this case.
Node IP addresses may still be added to [Hosts] but pre-existing (and possibly obsolete) addresses will not be removed.
Also note that the IP addresses specified for nodes during cluster configuration are primarily intended for SSR as opposed to RADIUS-specific configuration. If RADIUS traffic utilizes different IP addresses from SSR traffic, then it is up to the user to maintain spi.ini [Hosts].
