omitted. The identifier must be specified in standard ASCII notation of
IPv6 addresses (e.g. ::dead:beef). If the
\fIipv6cp\-use\-ipaddr\fR
-option is given, the local identifier is the local IPv4 address (see above).
+option is given, the local identifier is the local IPv4 address and the
+remote identifier is the remote IPv4 address (see above).

On systems which supports a unique persistent id, such as EUI\-48 derived
from the Ethernet MAC address, \fIipv6cp\-use\-persistent\fR option can be

.B active\-filter \fIfilter\-expression
Specifies a packet filter to be applied to data packets to determine
IPv6 interface identifier, even if the remote IPv6 interface
identifier was specified in an option.
.TP
+.B ipv6cp\-noremote
+Allow pppd to operate without having an IPv6 link local address for the peer.
+This option is only available under Linux. Normally, pppd will request the
+peer's IPv6 interface identifier (used for composing IPv6 link local address),
+and if the peer does not supply it, pppd will generate one for the peer.
+With this option, if the peer does not supply its IPv6 interface identifier,
+pppd will not ask the peer for it, and will not set the destination IPv6
+link local address of the ppp interface. In this situation, the ppp interface
+can be used for routing by creating device routes, but the peer itself cannot
+be addressed directly for IPv6 traffic until the peer starts announcing ICMPv6
+Router Advertisement or ICMPv6 Neighbor Advertisement packets. Note that IPv6
+router must announce ICMPv6 Router Advertisement packets.
+.TP
+.B ipv6cp\-nosendip
+Don't send our local IPv6 interface identifier to peer during IPv6 interface
+identifier negotiation.
+.TP
.B ipv6cp\-max\-configure \fIn
Set the maximum number of IPv6CP configure-request transmissions to
\fIn\fR (default 10).
