Configuration of a redundant Route Control server
The following configuration shows the basic operating principle of redundant Route Control
servers.
Redundancy connection
You need the following components to make the redundancy connection, depending on the
distance to be bridged:
Maximum distance

The availability of the complete system is also ensured even if one of the two Route Control
servers fails because the two Route Control servers form an independent redundancy node.
