I can explain a bit more.

For DNS interception (to Unbound, of course) I'm using PBR:

ip access-list extended intercept-ports
 permit udp any any eq domain
 permit tcp any any eq domain
 deny   ip any any
route-map redirect_dns permit 30
 match ip address intercept-ports
 set ip next-hop

which processes on router CPU and sometimes overload them.

WCCP, instead, processes on control plane, and not touch CPU to process.

Also, WCCP is fully transparent.

Why Unbound? This is simple. Because of we're use it as best caching DNS
server in our production infrastructure.

Well, if Unbound becomes fat - why not makes WCCP as configurable
non-default module, which will build on-demand, for such idiots like me?

Anyway. WCCP is caching related. Unbound is caching related. Why not
works together?

That would be logical, wouldn’t it?
