Define two routing policies, named apply_med_50 and apply_med_100 respectively. 
The first routing policy apply_med_50 configures the MED attribute as 50 for network 
1.0.0.0, and the second one apply_med_100 configures the MED attribute for the 
network as 100.  
[SwitchA] route-policy apply_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 apply_med_100 permit node 10 
[SwitchA-route-policy] if-match acl 2000 
[SwitchA-route-policy] apply cost 100 
[SwitchA-route-policy] quit 
# Apply apply_med_50 to the outbound routing update of neighbor SwitchC (193.1.1.2), 
and apply apply_med_100 to the outbound routing update of neighbor SwitchB 
(192.1.1.2).
