Configuring BFD for IPv6 BGP
Network requirements
As shown in Figure 121 , configure OSPFv3 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 1200::0/64.
Configure BFD over the link. Then if the link fails, BFD can quickly detect the failure and notify it to IPv6
BGP. Then the link Switch A<—>Switch D<—>Switch C takes effect immediately.
