So, my proposal:
```
high-availability
vrrp
group <number>
virtual-address (multi)
hello-source-address (ipv4)
peer-address (ipv4) # For unicast
disable <valueless>
run-transition-scripts
master (path)
backup (path)
fault (path)
preempt <valueless>
preempt-delay <int>
priority <int>
advertise-interval <int>
sync-group <name>
authentication
type <ah|plaintext-password>
password <text>
group6
<all same options but with IPv6 when applicable>
```
We need to research the issue of RFC compatibility, whether to try to include that at all or not.
