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

BFD for BGP configuration

Network requirements
As shown in
•
Configure OSPF as the IGP in AS 200.
•
Establish two IBGP connections between Router A and Router C. When both links are working,
Router C adopts the link Router A<—>Router B<—>Router 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 Router A<—>Router D<—>Router C takes effect
immediately.
