The subject of hooks has come up before, the result being that Lennart is
against the idea of hooks because they involve elements lower in the stack
calling up to elements higher in the stack, and that the appropriate thing to
do is for some service to monitor the state lower in the stack for the
condition before running the commands.
You might be able to replicate the behaviour by adding something like the
following; I haven't tested it myself, but systemd-networkd-wait-online
--interface=eth1 sounds promising.
[Unit]
Description=Post-up configuration for eth1
After=network.target
# If you want to block network-online.target until configuration has
finished
# then add Before=network-online.target
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/lib/systemd/systemd-networkd-wait-online --interface eth1
ExecStart=/usr/bin/ip addr add 2001:1111:0:222:33::/64 dev eth1
ExecStart=/usr/bin/ip addrlabel add prefix 2001:1111:0:222:33::/128 label
666
ExecStart=/usr/bin/ip addrlabel add prefix 2001:1111::/32 label
666
# Do `down` configuration with an ExecStop=
I don't understand enough of your configuration to suggest whether there might
be a way to do it natively with networkd.
