On Demand Routing, How to ?

ODR ???
Can anyone help me in Implementation Details of ODR(On Demand Routing).

The Scanario is 4 router(r1,r2,r3 & r4) connected in Hub and Spoke fashion
r1(hub router) ,r2,r3 & r4 (spoke routers) , and in a Non ISDN environment.

now how to Implement ODR in this network ? I want the config.

Thanks.

Just to be safe... you are positive this is what you want? This is not similar to DDR, nor is it a routing protocol. This is an extension of CDP.

If you do really want it. Make sure CDP enabled on all the routers, no dynamic routing protocols are configured on the spoke routers, and issue the 'router odr' command on the hub.

that is about it.

Take a look at the following:

an extra, remote sites must be stub only (with only one exit point towards the hub router), and with a statis default route pointing it.
