For security reasons, an IPv6 traffic filter has been applied under multiple interfaces on the local router. However, shortly after the traffic filter was applied, OSPFv3 neighbor adjacencies go down. What caused this issue?

B. The global anycast address must be added to the access control list to allow OSPFv3 to function.
C. The link-local addresses were explicitly denied.
D. IPv6 traffic filtering cannot be applied to more than one interface.
