(Optional) Disabling an Interface from Receiving and Sending OSPFv3 Packets

To prevent OSPFv3 routes from being received by other routers on the network and disable the local router from receiving updated routes, you can disable the local router's interface from receiving and sending OSPFv3 packets. After an interface is disabled from receiving and sending OSPFv3 packets, the interface can still advertise its routes but cannot exchange Hello packets with others. Therefore, no neighbor relationship can be established between the interface and others. This can enhance the networking adaptability of OSPFv3 and reduce system resource consumption.
