Synopsis

The replicate modul replicates packets to one or more home servers.

This module will open a new socket for each packet, copy the packet, and send the copy to a home server. Set control:Replicate-To-Realm = name, just as with Proxy-To-Realm. The realm must exist, the home_server_pool must exist, and the home_server must exist. The module will then replicate the packet to the realm(s) specified by the Replicate-To-Realm attribute(s). Each attribute can contain only one realm.

When packets are replicated, the module does not expect a reply. Any reply is ignored. Both Replicate-To-Realm and Proxy-To-Realm can be used at the same time.

To use this module, list replicate in the authorize or accounting section. Then, ensure that Replicate-To-Realm is set. The contents of the packet attribute list will be sent to the home server. The usual load-balancing, etc. features of the home server will be used.

radmin can be used to mark home servers alive/dead. Home servers are marked alive/dead in order to enable/disable replication to specific servers.

Packets can be replicated to multiple destinations. Just set Replicate-To-Realm multiple times. One packet will be sent for each of the Replicate-To-Realm attributes in the control list.

Note
 replication does not change any of the packet statistics. If you use radmin to look at the statistics for a home server, the replicated packets will cause no counters to increment. This is not a bug, this is how replication works.
