[SwitchA-Vlan-interface2] ip address 192.1.1.1 255.255.255.0
[SwitchA] interface Vlan-interface 3
[SwitchA-Vlan-interface3] ip address 193.1.1.1 255.255.255.0
# Enable BGP
[SwitchA] bgp 100
# Specify the destination network for BGP routes.
[SwitchA-bgp] network 1.0.0.0
# Configure BGP peers.
[SwitchA-bgp] group ex192 external
[SwitchA-bgp] peer 192.1.1.2 group ex192 as-number 200
[SwitchA-bgp] group ex193 external
[SwitchA-bgp] peer 193.1.1.2 group ex193 as-number 200
[SwitchA-bgp] quit
# Configure the MED attribute of Switch A.
