BGP route reflector configuration example

Network requirements
In Figure 62, all switches run BGP.
Between Switch A and Switch B is an EBGP connection, between Switch C and Switch B, and
•
between Switch C and Switch D are IBGP connections.
Switch C is a route reflector with clients Switch B and D.
•
• Switch D can learn route 20.0.0.0/8 from Switch C.

2. Configure BGP connections:
# Configure Switch A.
<SwitchA> system-view
[SwitchA] bgp 100
[SwitchA-bgp] router-id 1.1.1.1
[SwitchA-bgp] peer 192.1.1.2 as-number 200
[SwitchA-bgp] ipv4-family unicast
[SwitchA-bgp-ipv4] peer 192.1.1.2 enable
# Inject network 20.0.0.0/8 to the BGP routing table.
[SwitchA-bgp-ipv4] network 20.0.0.0
[SwitchA-bgp-ipv4] quit
[SwitchA-bgp] quit
# Configure Switch B.
<SwitchB> system-view
[SwitchB] bgp 200
[SwitchB-bgp] router-id 2.2.2.2
[SwitchB-bgp] peer 192.1.1.1 as-number 100
[SwitchB-bgp] peer 193.1.1.1 as-number 200
