Figure 83 :
• Configure OSPFv3 on Switch A, Switch B and Switch C and configure BFD over the link Switch
A<—>L2 Switch<—>Switch B.
• After the link Switch A<—>L2 Switch<—>Switch B fails, BFD can quickly detect the failure and
notify OSPFv3 of the failure. Then Switch A and Switch B communicate through Switch C.
