Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure OSPF to ensure 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-default] peer 3.0.2.2 as-number 200
[SwitchA-bgp-default] peer 2.0.2.2 as-number 200
[SwitchA-bgp-default] address-family ipv4 unicast
[SwitchA-bgp-default-ipv4] peer 3.0.2.2 enable
[SwitchA-bgp-default-ipv4] peer 2.0.2.2 enable
[SwitchA-bgp-default-ipv4] quit
[SwitchA-bgp-default] quit
# Create IPv4 basic ACL 2000 to permit 1.1.1.0/24 to pass.
[SwitchA] acl basic 2000
[SwitchA-acl-ipv4-basic-2000] rule permit source 1.1.1.0 0.0.0.255
[SwitchA-acl-ipv4-basic-2000] quit
# Create two routing policies to set the MED for route 1.1.1.0/24. The policy apply_med_50
sets the MED to 50, and the policy apply_med_100 sets the MED to 100.
[SwitchA] route-policy apply_med_50 permit node 10
