Linux tool for IPv6 unsolicited neighbor advertisements

Hello

Unsolicited neighbor advertisements is necessary to facilitate rapid service address takeover in a HA cluster. For IPv4 (ARP) you can use "arping -U", but so far I've had no luck finding any tool that can do something similar for IPv6.

EDIT: After searching more maybe the question is: Is this tool needed for IPv6? To me it looks like NDP should be able to solve this by it self.

• parasite6 and fake_advertiser6 are both part of THC-IPv6 They look like they would generate the necessary ICMPv6 packets to force L2/L3 mapping changes.

  Codeape : I will check that out.
