[Michael McConnell]

Thank you Charles, I am a little red in the face for having not tried / know that.

I’ll give it a go, thanks again for the help and prompt response!

I am using /32s, but I don't think there are any issues with /24s going into BGP. Let me know if you have any questions or I missed your questions in some way.
