Hi all,
In IPv6 whenever a NS packet is received,
and if the target address is link local, then second 16 bits from lsb
side are fileed with interface index. and while sending NA as reply
those bits in target address are made zero. Why is it done?
Acc. to rfc, those 16bits are part of 64 bit interface identifier. why
some bits are removed like this? and they are not considered in
checksum calculation also. why?
Thanks n Regards
