Class Of Restriction (COR) Lab Using GNS3

- First Keep in mind the following:

Each dial-peer or phone-dn can have one incoming COR list and one outgoing COR list:

- Incoming COR list means: the dial-peer or the phone can initiate calls or not.

- outgoing COR list means: who can call this dial-peer or phone or not.

- If no incoming COR list: this means that the dial-peer or the phone can call any one. Regardless of the outgoing COR setting on the phone called

- if no outgoing COR list: this means that anyone can call this dial-peer or phone regardless if the phone calling has an incoming COR set or not.

- If the incoming COR list is a superset or equal to the outgoing COR list this means that the call will succeed.

- If the incoming COR list is not a superset or equal to the outgoing COR list this means that the call will fail.

- When you begin configuration first you need to configure the outgoing COR.

- To deny a call when you configure the outgoing COR make sure that it is a superset of the incoming COR.

   Now it is Lab time:
