Ping Switch C on Switch A. Meanwhile, perform an active/standby main board 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.
