[c-nsp] IP RACL or CPP?

[Jose]

I'm trying to decide whether to implement IP RACLs or Control Plane 
Policing on our 7500s and I can't decide which is better.  We're 
currently running 12.0(27)S4 and we're being asked to implement some 
form of security for the router itself.  IP RACLs would cover this right 
now but there's the chance that we may upgrade the routers later this 
year to a version that supports CPP and I'd rather not kill myself 
trying to come up with an ACL that would be so complicated.  Should we 
just go ahead and use RACLs or wait until CPP is supported?  Is one 
better than the other?  Are there major differences?

Thanks for any tips.
