# Configure the MED attribute of Switch A.
Add an ACL on Switch A to permit network 1.0.0.0/8.
■
[SwitchA] acl number 2000
[SwitchA-acl-basic-2000] rule permit source 1.0.0.0 0.255.255.255
[SwitchA-acl-basic-2000] rule deny source any
Define two routing policies: set_med_50 and set_med_100, providing two
■
MED values for network 1.0.0.0 (50 and 100 respectively).
[SwitchA] route-policy set_med_50 permit node 10
[SwitchA-route-policy] if-match acl 2000
[SwitchA-route-policy] apply cost 50
[SwitchA-route-policy] quit
[SwitchA] route-policy set_med_100 permit node 10
[SwitchA-route-policy] if-match acl 2000
[SwitchA-route-policy] apply cost 100
Apply the routing policy set_med_50 to the exported route updates of Switch
■
C (193.1.1.2). Apply the routing policy set_med_100 to the exported route
updates of Switch B (192.1.1.2).
