Hey all,
I'm looking for an opinion from the group. I have an ARIN /21 assignment
and a new requirement for a second data center. Rather than ask for
another assignment, I would like to advertise one /22 from one location
and the other /22 from the second location both with the same asn. My
apps will work that way, so I don't have an issue internally, but I'm
looking for a broader base opinion on that.
Thanks a lot!

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.
