[FROG] VRRP setup with netplan on Ubuntu 20.04

[Oliver O'Boyle]

Just confirming that I did get this to work. Because I already had a
tagged vlan on that interface, I needed to keep it. I used the
existing netplan config to define the vlan, then created the macvlans
off of that. It looks like this:

3: ens224: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc mq state
UP group default qlen 1000
    link/ether 00:50:56:bd:d5:0f brd ff:ff:ff:ff:ff:ff
    inet6 fe80::250:56ff:febd:d50f/64 scope link
       valid_lft forever preferred_lft forever
4: vlan2049 at ens224: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc
noqueue state UP group default qlen 1000
    link/ether 00:50:56:bd:d5:0f brd ff:ff:ff:ff:ff:ff
    inet 192.168.145.195/26 brd 192.168.145.255 scope global vlan2049
       valid_lft forever preferred_lft forever
    inet6 2610:139:c001:3f:1801:f20a:0:2/64 scope global
       valid_lft forever preferred_lft forever
    inet6 fe80::250:56ff:febd:d50f/64 scope link
       valid_lft forever preferred_lft forever
5: vlan2049-4 at vlan2049: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000
qdisc noqueue state UP group default qlen 1000
    link/ether 00:00:5e:00:01:01 brd ff:ff:ff:ff:ff:ff
    inet 192.168.145.194/32 scope global vlan2049-4
       valid_lft forever preferred_lft forever
    inet6 fe80::200:5eff:fe00:101/64 scope link
       valid_lft forever preferred_lft forever
6: vlan2049-6 at vlan2049: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000
qdisc noqueue state UP group default qlen 1000
    link/ether 00:00:5e:00:02:01 brd ff:ff:ff:ff:ff:ff
    inet6 2610:139:c001:3f:1801:f20a:0:5/64 scope global
       valid_lft forever preferred_lft forever
    inet6 fe80::200:5eff:fe00:201/64 scope link
       valid_lft forever preferred_lft forever

Not the simplest config around....

I still haven't decided how to persist the macvlans yet, but at least
there are no conceptual issues with this level of subinterfaces.
