Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure OSPF to make sure that Switch A and Switch C are reachable to each other. (Details not
shown.)
3. Configure BGP on Switch A:
# Establish two IBGP connections to Switch C.
<SwitchA> system-view
[SwitchA] bgp 200
[SwitchA-bgp] peer 3.0.2.2 as-number 200
[SwitchA-bgp] peer 2.0.2.2 as-number 200
[SwitchA-bgp] ipv4-family unicast
[SwitchA-bgp-ipv4] peer 3.0.2.2 enable
[SwitchA-bgp-ipv4] peer 2.0.2.2 enable
[SwitchA-bgp-ipv4] quit
[SwitchA-bgp] quit
# Create ACL 2000 to permit 1.1.1.0/24 to pass.
[SwitchA] acl number 2000
[SwitchA-acl-basic-2000] rule permit source 1.1.1.0 0.0.0.255
[SwitchA-acl-basic-2000] quit
# Create two route policies, apply_med_50 and apply_med_100. Policy apply_med_50 sets the
MED for route 1.1.1.0/24 to 50. Policy apply_med_100 sets that to 100.
[SwitchA] route-policy apply_med_50 permit node 10
[SwitchA-route-policy-apply_med_50-10] if-match ip address acl 2000
[SwitchA-route-policy-apply_med_50-10] apply cost 50
