Comprehensive Explanation: A routing table contains information necessary for the router to determine the best path to forward packets. This includes the destination network or subnet (Destination/Mask), the next-hop address (the IP address of the next device in the path), and the cost (metric) associated with the route. MAC addresses are used at the Data Link layer (Layer 2) for local network communication and are not part of the routing table, which operates at the Network layer (Layer 3).

The country-code command is used on an AC (Access Controller) to specify the country code, which aligns the wireless settings with local regulatory standards. Setting the correct country code ensures compliance with regional RF (Radio Frequency) regulations, such as frequency bands and transmission power limits​.

Comprehensive Explanation: In OSPF (Open Shortest Path First), a router first synchronizes its Link-State Database (LSDB) with its neighbors by exchanging link-state information. Only after this synchronization process is complete does the router transition to the Full state. The Full state indicates that the router has fully converged with its OSPF neighbors and has a complete and up-to-date view of the network topology. Therefore, the router enters the Full state after synchronizing its LSDB, not before.

Comprehensive Explanation: A routing table contains several key elements:

Cost: Also known as metric, this indicates the cost associated with reaching a specific destination, such as the number of hops or link speed.

Next-hop address: This is the IP address of the next device along the route that packets should be forwarded to.

Protocol: The routing protocol (e.g., OSPF, RIP) that determined the route.

Interface: The physical or logical interface through which the router sends packets to reach the destination.

Destination/Mask: The destination network or subnet and the associated subnet mask define the range of IP addresses for which this route is valid. These elements together allow routers to efficiently forward traffic to the correct destinations.

Given correct configuration, hosts within the same subnet should be able to communicate, so the host at 10.0.12.1 can ping the host at 10.0.12.2. This scenario assumes correct interconnectivity and absence of firewall or ACL rules that would block the communication​.

Detailed Explanation:The command forward-mode direct-forward is used to configure the AC to enable direct forwarding, meaning that the AP will forward user data packets directly to the network without tunneling them through the AC, improving efficiency by reducing the load on the AC​.

Detailed Explanation:The EUI-64 format splits a MAC address into two parts and inserts "FFFE" in the middle. The Universal/Local (U/L) bit is flipped, so a valid EUI-64 address would be 02E0-FCEF-FFFE-0FEC​.
