Summary

Currently, the templates and settings for both conntrack-sync and DHCP HA are all IPv4 only for the "state sync/signalling" parts. Consider add support for IPv6. The underlying softwares used (keepalived and Kea) both support IPv6 for those signalling transports, but the VyOS configuration generation is preventing this. Specifically, considering changing:

• service conntrack-sync interface <interface> peer <address>
• service conntrack-sync listen-address <address>
• service conntrack-sync mcast-group <address>
• service conntrack-sync interface <interface> (fails if intf is IPv6 only)
• service dhcp-server high-availability source-address <address>
• service dhcp-server high-availability remote <address>

to be IPv6 compatiable.

Use case

Providing HA in IPv6-mostly/only/dual stack (w/ IPv6 preferred) networks.
