I've run into this issue before. We didn't want to have a different set of
route servers with a different group of peers so what we did was had the
routers that the caching take in a BGP feed from the existing route servers
and then just allowed the much smaller amount of request (reverse) traffic
bounce through the peer that is advertising the /24 the /25 is part of. Of
course if you have the address space, go ahead and burn a /24.

Also, IPv6 address space is much easier to get so if you increase the size
of your advertised block to at least a /48 you can then peer normally with
the caching engines.
