What does R1 use as the MAC address of the destination when constructing the frame that will go from R1 to Server B? If the destination MAC address that corresponds to the IPv4 address is not in the ARP cache, R1 sends an ARP request. R1 uses the destination MAC address of S1. The packet is encapsulated into a PPP frame, and R1 adds the PPP destination address to the frame. R1 leaves the field blank and forwards the data to the PC.
If the destination MAC address that corresponds to the IPv4 address is not in the ARP cache, R1 sends an ARP request.
What is a characteristic of a static route that matches all packets? It uses a single network address to send multiple static routes to one destination address.
