Receive-Instantiation Procedure
The receive-instantiation procedure is called from the receive procedure
when a new peer is discovered. It initializes the peer variables and
mobilizes the association. If the message is from a peer operating in
client mode (3), the host mode is set to server mode (4); otherwise, it
is set to symmetric passive mode (2). The authentication variables are
used only if the authentication mechanism described in Appendix C is
implemented. If implemented, only properly authenticated non-configured
peers can become the synchronization source.
