.B mtu \fIn
Set the MTU [Maximum Transmit Unit] value to \fIn\fR. Unless the
peer requests a smaller value via MRU negotiation, pppd will
request that the kernel networking code send data packets of no more
-than \fIn\fR bytes through the PPP network interface.

Enables the "passive" option in the LCP. With this option, pppd will

\fIipcp-accept-remote\fR options are given, respectively.
.TP
+.B ipv6 \fI<local_interface_identifier>\fR,\fI<remote_interface_identifier>
+Set the local and/or remote 64-bit interface identifier. Either one may be
+omitted. The identifier must be specified in standard ascii notation of
+IPv6 addresses (e.g. ::dead:beef). If the
+\fIipv6cp-use-ipaddr\fR

+.B ipv6cp-max-configure \fIn

+Set the maximum number of IPv6CP configure-NAKs returned before starting

+.B ipv6cp-max-terminate \fIn
+Set the maximum number of IPv6CP terminate-request transmissions to

+.B ipv6cp-restart \fIn
+Set the IPv6CP restart interval (retransmission timeout) to \fIn\fR

.B ipx
Enable the IPXCP and IPX protocols. This option is presently only
supported under Linux, and only if your kernel has been configured to
only be required if the peer is buggy and gets confused by requests
from pppd for IPCP negotiation.
.TP
+.B noipv6
+Disable IPv6CP negotiation and IPv6 communication. This option should
+only be required if the peer is buggy and gets confused by requests
+from pppd for IPv6CP negotiation.

.B noipdefault
Disables the default behaviour when no local IP address is specified,
which is to determine (if possible) the local IP address from the
specified.
