Routing VLANs

Let s say  I have 10  Layer 2 Switches with 2 VLans on each switch, then connect those 10 Switches to a Core/Distribution Layer 3 Switch.  Then Route all Vlans from Core Switch to Router R1

If I am not wrong I will need to Configure a Trunk port on each L2 Switch and connect them (all Trunk ports)to Core/Distribution Layer 3 Switch ports. Then configure IP Routing command within Core/Distribution Layer 3 Switch so that VLANs can communicate between themselve. At this point PCs on L2 Switch will be able to communicate between themselves...

Now if I need to route the VLANs from Core/Distribution Layer 3 Switch to Router R1 , what should I configure on Core/Distribution Layer 3 Switch and R1 ?

Thank you

Dynamic routing (OSPF, EIGRP or IS-IS) or static routes. If you need to route every traffic that is not local traffic - default route to R1 is enough. On R1 you need to configure route(s) (static or dynamic) that will point to core as next hop to reach you networks from R1. Dynamic routing is preferred.

OK , for instance

Core# IP route 0.0.0.0 0.0.0.0  IP address of the Router Interface

How do you do it from R1 back to the Core switch ?
