4. Configure attributes for route 1.0.0.0/8, making Switch D give priority to the route learned from Switch C: { (Method I.) Configure a higher MED value for the route 1.0.0.0/8 advertised from Switch A to peer 192.1.1.2: # Define an ACL numbered 2000 to permit route 1.0.0.0/8.

Configure different local preferences on Switch B and C for route 1.0.0.0/8, making Switch D give priority to the route from Switch C: # Define an ACL numbered 2000 on Router C, permitting route 1.0.0.0/8.
