Management
Options
noipv4 Specify this option to disable IPCP (NCP
for IPv4 over PPP) negotiation. No IPv4
datagram will pass through the link. You
need to specify this option to establish a
point-to-point link for IPv6 packets, that is,
to negotiate only IPV6CP messages.
Note: To look up the systems file, you must
specify the IPv4 destination address, even
if you wish to configure only IPv6
datagrams by choosing the ipv6 and
noipv4 options on the command line.
