4. Configure different attribute values for the route 1.0.0.0/8 to make Router D give priority to the

route learned from Router C:

{ (Method 1.) Specify a higher MED value for the route 1.0.0.0/8 advertised to 192.1.1.2 to make

Router D give priority to the route learned from Router C:

# Define ACL 2000 to permit the route 1.0.0.0/8.

[RouterA] acl number 2000

[RouterA-acl-basic-2000] rule permit source 1.0.0.0 0.255.255.255

[RouterA-acl-basic-2000] quit

# Define routing policy apply_med_50 that sets the MED value of route 1.0.0.0/8 to 50, and

routing policy apply_med_100 that sets the MED value of route 1.0.0.0/8 to 100.

[RouterA] route-policy apply_med_50 permit node 10

[RouterA-route-policy-apply_med_50-10] if-match ip address acl 2000

[RouterA-route-policy-apply_med_50-10] apply cost 50

[RouterA-route-policy-apply_med_50-10] quit

[RouterA] route-policy apply_med_100 permit node 10

[RouterA-route-policy-apply_med_100-10] if-match ip address acl 2000
