[Ns-developers] [Fwd: [Bug 757] IPv6 link-local address on non-ARP interfaces]

[Sebastien Vincent]

Hi guys,

The bug 757 is about IPv6 link-local on non-ARP devices such as PPP.

In general PPP devices do not have a link-layer address and they use 
IPv6 Control Protocol to obtain a 64-bit identifier (see RFC5072) and 
then autoconfigure their link-local address.

In order to use IPv6 over PPP now, the quick way is to add a NdiscCache 
to PPP (currently NdiscCache is added only to ARP-like devices) and then 
Neighbor Discovery messages (NS, NA, RA, RS) will contains link-layer 
address and like I said in real world PPP devices have not a link-layer 
address.

WDYT about this workaround before an IPv6CP implementation ?

Regards,
