III. Configuration procedure
1) Configure Switch A.
[SwitchA] interface vlan-interface 2
[SwitchA-Vlan-interface2] ip address 192.1.1.1 255.255.255.0
[SwitchA-Vlan-interface2] interface Vlan-interface 100
[SwitchA-Vlan-interface100] ip address 1.1.1.1 255.0.0.0
[SwitchA-Vlan-interface100] quit
[SwitchA] bgp 100
[SwitchA-bgp] group ex external
[SwitchA-bgp] peer 192.1.1.2 group ex as-number 200
[SwitchA-bgp] network 1.0.0.0 255.0.0.0
2) Configure Switch B.
# Configure VLAN 2.
[SwitchB] interface Vlan-interface 2
[SwitchB-Vlan-interface2] ip address 192.1.1.2 255.255.255.0
# Configure VLAN 3.
[SwitchB] interface Vlan-interface 3
[SwitchB-Vlan-interface3] ip address 193.1.1.2 255.255.255.0
# Configure a BGP peer.
