Wireshark
The system doesn'nt send correct ndp neighbor solicitation messages for ipv6.
For these messages, carp uses the hardware-mac address of the interface and not
the virtual mac for the carp-ip. This ends up in packet-loss for the virtual
ipv6 address.
On ipv4, the arp cache shows the virtual mac entry. (correct)
On ipv6, the ndp cache shows the hardware mac entry. <--problem
The interface is configured with two ipv4 virtual addresses and one ipv6
virtual address.
The ipv4 addresses work like a charm.
The Wireshark attachement shows that the server sends the hardware-mac-address
instead of the virtual mac address ( 00:00:5e:00:01:01 )
