On the network shown in the figure, EBGP peer relationships are established between neighboring routers through directly connected interfaces. The AS number is 6500X, where X is the number of the router. Both R1 and R4 have static routes to 192.168.1.0/24, which are imported to BGP through the import-route command.
By default, in the routing table of R3, which of the following is the AS_Path attribute carried in the route to 192.168.1.0/24?

In the OSPFv3 network shown in the figure, the interconnected ports of R1, R2, and R3 have OSPFv3 enabled, and the Router ID of each device is 10.0.XX, where X is the device number.
Check the detailed information of a certain LSA on R3. From the output information, it can be inferred that the LSA is generated by R2, and it describes the IPv6 prefix address associated with the Network-LSA.
