RTC-ospf-1] area 0
RTC-ospf-1-area-0.0.0.0] network 192.168.1.0 0.0.0.255
Judging from the above configuration, ________

• A.RTA and RTB, RTA and RTC can establish neighbors
• B.RTA and RTB, RTA and RTC cannot establish neighbors
• C.A neighbor cannot be established between RTA and RTB, but a neighbor can be established between RTA and RTC

In the network shown in the figure, the related 6to4 tunnel configuration is correct. When RTA receives the IPv6 data packet sent by PC1 to the destination address 2002:303:314:202:206:101:118:1, this data packet _______.

• A.It will match the route with the next hop pointing to the 6to4 tunnel, encapsulate the message and send it to RTC
• B.It will match the route with the next hop to the physical interface and forward it by the physical interface
• C.No route matching, just discard
• D.It will match the route with the next hop to the 6to4 tunnel, encapsulate the message and send it to RTB
