An administrator attempts to change the router ID on a router that is running OSPFv3 by changing the IPv4 address on the router loopback interface. Once the IPv4 address is changed, the administrator notes that the router ID did not change. What two actions can the administrator take so that the router will use the new IPv4 address as the router ID? (Choose two.)
Copy the running configuration to NVRAM.
Reboot the router.
Disable and re-enable IPv4 routing.
Shut down and re-enable the loopback interface.
Clear the IPv6 OSPF process.

Refer to the exhibit. An administrator is trying to configure PAT on R1, but PC-A is unable to access the Internet.

The NAT source access list matches the wrong address range.
The inside and outside NAT interfaces have been configured backwards.
The inside global address is not on the same subnet as the ISP.
The address on Fa0/0 should be 64.100.0.1.
