[Switch A] acl number 2000
[Switch A-acl-basic-2000] rule permit source 1.0.0.0 0.255.255.255
[Switch A-acl-basic-2000] rule deny source any
z Define two route policies, one is called apply_med_50 and the other is called
apply_med_100. The first MED attribute with the route policy as network 1.0.0.0 is
set as 50, while the MED attribute of the second is 100.
[Switch A] route-policy apply_med_50 permit node 10
[Switch A-route-policy] if-match acl 2000
[Switch A-route-policy] apply cost 50
[Switch A-route-policy] quit
[Switch A] route-policy apply_med_100 permit node 10
[Switch A-route-policy] if-match acl 2000
[Switch A-route-policy] apply cost 100
[Switch A-route-policy] quit
z Apply route policy set_med_50 to egress route update of Switch C (193.1.1.2),
and apply route policy set_med_100 on the egress route of Switch B (192.1.1.2)
[Switch A] bgp 100
[Switch A-bgp] peer 193.1.1.2 route-policy apply_med_50 export
[Switch A-bgp] peer 192.1.1.2 route-policy apply_med_100 export
2) Configure Switch B:
[Switch B] interface vlan-interface 2
[Switch B-Vlan-interface2] ip address 192.1.1.2 255.255.255.0
[Switch B] interface vlan-interface 4
[Switch B-Vlan-interface4] ip address 194.1.1.2 255.255.255.0
[Switch B] ospf
[Switch B-ospf] area 0
[Switch B-ospf-area-0.0.0.0] network 194.1.1.0 0.0.0.255
[Switch B-ospf-area-0.0.0.0] network 192.1.1.0 0.0.0.255
[Switch B] bgp 200
[Switch B-bgp] undo synchronization
[Switch B-bgp] peer 192.1.1.1.1 as-number 100
[Switch B-bgp] peer 194.1.1.1.1 as-number 200
3) Configure Switch C:
[Switch C] interface Vlan-interface 3
[Switch C-Vlan-interface3] ip address 193.1.1.2 255.255.255.0
