The output shows that Switch D has learned the network 1::/64 from Switch C through route reflection.
BFD for IPv6 BGP configuration example
Network requirements
As shown in Figure 69, configure OSPFv3 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 1200::0/64.
Configure BFD over the path. Then if the path fails, BFD can quickly detect the failure and notify it to IPv6
BGP. Then the path Switch A<—>Switch D<—>Switch C takes effect immediately.
