I wanted to add that if we want to carry Layer 2 all the way up to the 6509 and terminate the Layer 3 at the core layer and that core layer is composed of 2 6509s for redundancy (see diagram), you are still going to need to do VRRP.
If we move the Layer 3 termination to the Aggregation layer, we don't need VRRP so long as you always use 4200s in a Virtual Chassis configuration. In this mode, we do VC-LAG (Virtual-Chassis LAG) between the two 4200 VC Members and the access layer device. So this is probably the best approach since we don't have the wiggle room to do VRRP (readdressing, etc.)...
