In the last post I was taking a look at sharing a prefix list in an organization. That way I don’t have to remember a list of IP addresses or CIDRs and if they change, I can change them in one place.

The next thing I want to do is take a look at creating a shared security group and see if there are any pros and cons to doing that as opposed to a prefix list.

There are some instructions here, but I’m going to just use the same approach I used in the last post.
