You should attempt to advertise the /21 at each site along with the
site's /22
If you dont have dedicated interconnectivity between the sites,
tunneling *carefully* should do the trick.
This will ensure that if/when those who filter on strict allocation
boundaries dont hear your /22, there will still be reachability, even if
suboptimal, to your sites.
