Lab Simulation 15 Guidelines This is a lab item in which tasks will be performed on virtual devices - Refer to the Tasks tab to view the tasks for this lab item. - Refer to the Topology tab to access the device console(s) and perform the tasks. - Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window. - All necessary preconfigurations have been applied. - Do not change the enable password or hostname for any device. - Save your configurations to NVRAM before moving to the next item. - Click Next at the bottom of the screen to submit this lab and move to the next question. - When Next is clicked the lab closes and cannot be reopened. Topology Tasks Refer to the topology. All physical cabling is in place. Routers R3 and R4 are fully configured and inaccessible. Configure static routes for various connectivity to the ISP and the LAN, which resides on R4. 1. Configure a default route on R2 to the ISP 2. Configure a default route on R1 to the ISP 3. Configure R2 with a route to the Server at 10.0.41.10 4. Configure R1 with a route to the LAN that prefers R3 as the primary path to the LAN Answer: R1: config t ip route 0.0.0.0 0.0.0.0 10.0.12.2 ip route 10.0.41.0 255.255.255.0 10.0.13.2 R2: config t ip route 0.0.0.0 0.0.0.0 209.165.200.225 ip route 10.0.41.10 255.255.255.255 10.0.24.2

Explanation

Approach. Each task requires a specific static route command on Cisco IOS. Task 1 & 2 use a default route (ip route 0.0.0.0 0.0.0.0 <ISP-facing-next-hop>) on R2 and R1 respectively - this catches all traffic with no more-specific match and forwards it toward the ISP. Task 3 on R2 requires a host route to 10.0.41.10 (ip route 10.0.41.10 255.255.255.255 <next-hop>), targeting only that server. Task 4 on R1 requires a static route to the LAN subnet via R3 as the primary next-hop; to also have a backup path (floating static route), a second route to the same LAN is added via a different next-hop with a higher administrative distance (e.g., AD=2 vs default AD=1), so R3 is preferred unless it fails. All configurations must be saved with copy running-config startup-config (or wr) before clicking Next.

Concept tested. IPv4 static routing on Cisco IOS - including default routes (0.0.0.0/0), host-specific routes (/32), and floating static routes (manipulating administrative distance to establish primary vs. backup path preference).
