Yes, we do this for several clients. We route them a smaller than 24 block over a tunnel.
Which bring up an interesting question. Will there be a time where the smallest block size recognized will be something smaller than a /24? /25, /26 ? Most modern routers have the horsepower to deal with larger route tables. I know of dozens, if not hundreds of small ISPs that can’t participate in BGP because they don’t have big enough blocks. Many others who do are not utilizing their /24 so it just kinda sits there. They have to have their provider assigned IP space be advertised. Does not help them getting on to an IX though. I know I know IPV6 is the answer not going to accepting smaller blocks.
