How about if each of such internal site uses the same *single* private 
AS number and you perform loop detection/troubleshooting by use of SOO 
extended community ?

It is local to you to assign it's value (6 octets seems wide enough) and 
it has been already widely implemented.

Today it is used mainly for multihomed VPN sites, but it could be 
applied equally well to your internal sites.

Thx,
R.
