[SwitchC-bgp] peer 9.1.1.1 as-number 65009
# Enable GR capability for BGP.
[SwitchC-bgp] graceful-restart
# Enable Switch C to exchange IPv4 unicast routing information with Switch B.

Verifying the configuration
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.

BFD for BGP configuration example

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 paths are working,
•
Switch C adopts the path Switch A<—>Switch B<—>Switch C to exchange packets with network
1.1.1.0/24. Configure BFD over the path. If the path fails, BFD can quickly detect the failure and
notify it to BGP. Then the path Switch A<—>Switch D<—>Switch C takes effect immediately.
