MSFC1 receives the packet, rewrites the packet, and forwards the packet to host B. In an effort to rewrite the packet, MSFC1 sends an ARP request for host B because the host resides off a straight related interface.
With HSRP, members from the Digital router team constantly Trade status messages. 1 router can assume the routing duty of A different if a router goes from commission for both prepared or unplanned good reasons. Hosts are configured with one default gateway and proceed to ahead IP packets to your steady IP and MAC handle. The changeover of equipment that do the routing is transparent to the end workstations.
