The option contains one or more IPv4 addresses that the client may use. The

 

 

current use of this option is for downloading configuration from a VoIP server

 

 

via TFTP; however, the option may be used for purposes other than

 

 

contacting a VoIP configuration server.

 

 

 

7.4 PPP Interfaces

Use PPPoE/PPTP interfaces to connect to your ISP. This way, you do not have to install or manage PPPoE/PPTP software on each computer in the network.
