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.
