feat(icmp): add IPv6 multicast neighbor discovery - #155
Merged
Conversation
Add an ICMPv6 discovery subcommand that sends a correlated echo request to a link-local multicast group and emits neighbor-cache compatible results. Select link-local source addresses for link-local multicast targets and filter incoming traffic to matching echo replies.
