A network engineer is troubleshooting a small LAN network with one border router, GW01 thatconnects to the Internet Service Providers (ISP) network. GW01 uses its Serial 0/2/1 interface toconnect 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 organization’s LAN side of the network. Provide as much information as possible includingspecific commands and all required parameters. (5 points)2. A Cisco router has learned the following destination prefix 209.175.28.0 /24 from its directlyconnected network, static routing, and via dynamic routing. List in order of importance the waythe router will go about inserting the route in its final routing table assuming everything is nowworking. What is the Cisco router using to make that decision? Explain when the dynamicrouting 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 thefollowing output. What would be the static route commands that you would type on R2in order to reach R1s subnets. Provide complete configuration command withdestination prefixes and next-hop information or exit interface. Assume R1 is alreadyconfigured. (5points)
