PPPoA command reference
iMG/RG Software Reference Manual (ADSL Port)
8-126
Description
This command controls whether the PPP
Internet Protocol Control Protocol
(IPCP) can
request a DNS server IP address for a remote PPP peer. Once IPCP has discovered the
DNS server IP address, it automatically gives the address to the local DNS client so that
a connection can be established.
You must have the DNS client process included in your image build in order to use this
protocol.

The following table gives the range of values for each option that can be specified with
this command and a default value (if applicable).

{ENABLED|DISABLED}
Description
This command allows you to enable/disable whether your system can transmit and
receive packets containing HDLC headers. If you want LLC packets to be transmitted and
received instead of/as well as HDLC packets, use the

multiplexed (VC Mux). PPP determines which format to use to transmit/receive packets
by ‘learning’ the format information from incoming packet headers.
