Description: Pre 9.0 multilines can only negotiate LCP over 1 line. The exact line which LCP will occur on is unknown. So in order to handle this situation we will wait until we receive an LCP Request before we attempt to negotiate LCP by setting the mode to PPP_MODE_PEER_SOLICITED_LCP_NEGO. If we are using this line as a single PPP Line or we are sure our peer can handle LCP on all the members of the multiline, PPP_MODE_NORMAL should be selected. Multilink is a PPP protocol extension which provides restoration of packets which arrive out of sequence, a possibility with multiple lines. Multilink monitor, in conjunction with other configuration data allows the throughput of a line to be monitored. Additional lines can be brought into the bundle and taken down dynamically in response to data traffic volume and other conditions.
