Static and Dynamic Routing
1. A network engineer is troubleshooting a small LAN network with one border router, GW01 that
connects to the Internet Service Providers (ISP) network. GW01 uses its Serial 0/2/1 interface to
connect to the ISPs router. Everyone on the LAN network lost connectivity to the Internet. Upon
troubleshooting the issue, the network engineer notices the following message after typing
show ip route.
Gateway of last resort required but not set.
What do you suggest the network engineer do to rectify this issue? Assume the problem is only
on the organizations LAN side of the network. Provide as much information as possible including
specific commands and all required parameters. (5 points)
2. A Cisco router has learned the following destination prefix 209.175.28.0 /24 from its directly
connected network, static routing, and via dynamic routing. List in order of importance the way
the router will go about inserting the route in its final routing table assuming everything is now
working. What is the Cisco router using to make that decision? Explain when the dynamic
routing protocol information will be utilized in the routing table. (5 points)
3. The show ip interface brief command executed on router1 R1 and R2 generated the
following output. What would be the static route commands that you would type on R2
in order to reach R1s subnets. Provide complete configuration command with
destination prefixes and next-hop information or exit interface. Assume R1 is already
configured. (5points)
