The forwarding table requires the following three pieces of information so that the device can forward traffic:
B. next hop IP address
- The next hop IP address is used to determine the next point to which the packet should be sent on its way to the final destination.
C. outgoing interface name
- The outgoing interface name indicates which physical or logical interface the packet should be sent out of.
E. next hop MAC address
- The next hop MAC address is needed for Layer 2 forwarding within the local network, ensuring the packet is delivered to the correct device on the next hop.
Explanation of Other Options:
- A. BGP local preference value: This value is used in BGP routing decisions to select the best path but is not used in the forwarding table for actual packet forwarding.
- D. OSPF metric value: The OSPF metric is used to calculate the best path within the OSPF routing protocol but is not directly included in the forwarding table.
