The configurations of SwitchB and SwitchC are similar to the configuration of SwitchA, and
are not mentioned here.
Step 2 Assign an IP address to each VLANIF interface.
[SwitchA] interface vlanif 10
[SwitchA-Vlanif10] ip address 200.1.4.1 24
[SwitchA-Vlanif10] quit
[SwitchA] interface vlanif 20
[SwitchA-Vlanif20] ip address 200.1.2.1 24
[SwitchA-Vlanif20] quit
The configurations of SwitchB and SwitchC are similar to the configuration of SwitchA, and
are not mentioned here.
Step 3 Configure IBGP connections.
# Configure Switch A.
[SwitchA] bgp 10
[SwitchA-bgp] router-id 1.1.1.1
[SwitchA-bgp] peer 200.1.4.2 as-number 30
[SwitchA-bgp] peer 200.1.2.2 as-number 20
[SwitchA-bgp] import-route direct
# Configure Switch B.
[SwitchB] bgp 20
[SwitchB-bgp] router-id 2.2.2.2
[SwitchB-bgp] peer 200.1.2.1 as-number 10
[SwitchB-bgp] peer 200.1.3.2 as-number 30
[SwitchB-bgp] import-route direct
[SwitchB-bgp] quit
# Configure Switch C.
[SwitchC] bgp 30
[SwitchC-bgp] router-id 3.3.3.3
[SwitchC-bgp] peer 200.1.3.1 as-number 20
[SwitchC-bgp] peer 200.1.4.1 as-number 10
[SwitchC-bgp] import-route direct
[SwitchC-bgp] quit
# Check the routing table advertised by Switch B to peer 200.1.3.2. Take the routing table
advertised by Switch B to Switch C as an example. You can find that Switch B advertises the
routes destined to the network segment between Switch A and Switch C.
