III. Configuration procedure

1) Configure IP addresses for interfaces (omitted)

2) Configure BGP confederation

# Configure Switch A.

<SwitchA> system-view

[SwitchA] bgp 65001

[SwitchA-bgp] router-id 1.1.1.1

[SwitchA-bgp] confederation id 200

[SwitchA-bgp] confederation peer-as 65002 65003

[SwitchA-bgp] peer 10.1.1.2 as-number 65002

[SwitchA-bgp] peer 10.1.1.2 next-hop-local

[SwitchA-bgp] peer 10.1.2.2 as-number 65003

[SwitchA-bgp] peer 10.1.2.2 next-hop-local

[SwitchA-bgp] quit

# Configure Switch B.

<SwitchB> system-view

[SwitchB] bgp 65002

[SwitchB-bgp] router-id 2.2.2.2

[SwitchB-bgp] confederation id 200

[SwitchB-bgp] confederation peer-as 65001 65003
