[SwitchB-bgp] peer 200.1.1.2 as-number 65008
# Configure the iBGP connection.
[SwitchB-bgp] peer 9.1.1.2 as-number 65009
# Inject networks 200.1.1.0/24 and 9.1.1.0/24 to the BGP routing table.
[SwitchB-bgp] network 200.1.1.0 24
[SwitchB-bgp] network 9.1.1.0 24
# Enable GR capability for BGP.
[SwitchB-bgp] graceful-restart
Configure Switch C.

[SwitchC] bgp 65009
[SwitchC-bgp] router-id 3.3.3.3
[SwitchC-bgp] peer 9.1.1.1 as-number 65009

Verify the configuration.
4.
Ping Switch C on Switch A. Meanwhile, perform an active/standby switchover on Switch B. The ping
operation is successful during the whole switchover process.

Configuring BFD for BGP

Network requirements
As shown in
• Configure OSPF as the IGP in AS 200.
Establish two iBGP connections between Switch A and Switch C. When both links are working,
•
Switch C adopts the link Switch A<—>Switch B<—>Switch C to exchange packets with network
1.1.1.0/24. Configure BFD over the link. Then if the link fails, BFD can quickly detect the failure and
notify it to BGP. Then the link Switch A<—>Switch D<—>Switch C takes effect immediately.
