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 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.
