The call Statement

Syntax

call <server> {
    [ statements ]
}

The call statement will run the current request through another virtual server. Once that virtual server is complete, the request will continue being processed in the original virtual server.

<server>: The virtual server which will process the request.

The called virtual server must have the same namespace value as the calling virtual server.

The called virtual server will execute the request as if it had been received from the network. For example, if the packet is a RADIUS Access-Request, then the called virtual server will process the recv Access-Request section, followed by the authenticate <type> section, followed by the send Access-Accept section.
[ statements ]: Once the called virtual server has finished, the [ statements] from inside of the call section will be executed.

The return code of the call statement is taken from the final return code of the called virtual server.

Example

Processing the contents of a DHCPv6 relay-message by using a subrequest and recursively calling the DHCPv6 virtual server.

subrequest &Packet-Type &Relay-Message &reply.Relay-Message {
    call dhcpv6 {}
}
