Static Routing Lab Report/Answers Prereq: Linux Lab, Wireshark Lab, Switch Lab Network Set-up: 3. a. works b. “connect: Network is unreachable” c. “connect: Network is unreachable” 1. You should notice both ARP and ICMP packets. ICMP packets represent ping requests and responses that were sent to the target. ARP is translating an IP to a mac address. Who has 10.0.1.12? Tell 10.0.1.11 10.0.1.12 is at 00:00:00:00:00:00 2. From PC1, PC2 eth0 is reachable. From PC2, PC1 and router are reachable. From Router1, PC2 and PC3 are reachable. From PC3 Router1 is reachable. To make each device able to communicate with eathother device, one could put them all on the same subnet, ie. Putting them all on a single VLAN. Commands: Ip route 10.21.0.0 255.255.0.0 10.11.0.4 : This command will create a route in the router from a next hop of 10.11.04 to the subnet 10.21.0.0. We are telling the router that the way to access this subnet, is through this gateway. ip route 10.0.2.31 255.255.255.255 10.0.1.21 : This command is the same as the above, except we have narrowed it down to a single IP. We are saying that the only way to access this host is through this gateway. ip route 0.0.0.0 0.0.0.0 10.0.4.4 : This example tells us that we can reach everything by using he next hop of 10.0.4.4. That is to say, that 10.0.4.4 is the default gateway for this router.
