I didn't have much reason for selecting 9999 other than it was easy to identify visually. And obviously, I have safe-guards to not leak those communities into other networks.
I would recommend against using other public ASNs for internal signalling, ASN part should be considered property of given ASN. AS9999 might want to use 9999 to signal particular source where route was learned and your customer might want to do TE with it. Now you must delete them on ingress and rob your customers of this possibility. Hopefully future community (*wink*wink*blink*blink* Raszuk) standards will explicitly state that this is faux pas. -- ++ytti
