ccna remote jobs.As you can see from Figure 5.4, PC.C has been moved from the left segment to the right segment, but its IP has not changed. However, PC-A still assumes that PC.C is in the same network segment as it. To solve this reachability problem, two tasks are required.. Configure a static host route on the router to route traffic sent to the device that has moved to the segment where that device is located.. Enable the Proxy ARP feature on the router interface connected to the network segment where this device was originally located.Proxy ARP allows the router to use its own MAC address to answer ARP queries when the device being queried is not in the current network segment. For example, in Figure 5.4, PC-C does not see the ARP query broadcast sent by PC-A, and the router has a static route to 1.1.1.3, which points to the segment on the right, so the router will respond using its own MAC address (0000.0CCC.2222) when it receives an ARP request for query 1.1.1.3. This creates the illusion that PC-A thinks that PC-C is in the same network segment as it. Next.PC-A forwards the traffic to the router (thinking it is sending directly to PC-C) and the router will forward the traffic to the correct network segment. PC-A Figure 5.4 Proxy ARP Example PC-B 1.1.1.1 2.2.22 Practical Experience 0000.0CCC.1111 0000.0CCC.4444 It is not recommended to do what is demonstrated in Figure 5.4 in a network: after moving a device from one network segment to another, the IP addressing information of the device should be modified accordingly to the network number of the new segment. Proxy ARP may only be required in two cases: when the application has hard-coded the IP address so that it cannot be modified after moving the server to another segment, and when IP addressing information is assigned to a remote IPsec client.3. RARPRARP is the opposite of ARP. In ARP, the device knows the Layer 3 address, but not the data link layer address; while using RARP to requestPC-C 1.1.1.3in which the device does not have an IP address and wants one (the only address the device has is a MAC address) Common protocol packets using RARPinclude BOOTP and DHCP.
