Each logical-router instance takes the full resources of a complete
router. For example, 2 LR's with full BGP feeds will result in 2 rpd
instances using 200MB of ram each (or whatever it is that they use these
days). An M7i will never get anywhere near that, you'd be lucky just to
get 2 working.

But honestly you don't need 15 routers in a JNCIE lab, let alone 24.
There is no reason you need to implement the entire thing all at once,
just work with the individual skills a couple routers at a time, and 
don't take full tables. A few representative routes in IGP and IBGP will 
be fine.
