Why would you want to disable CDP on an interface or globally?
You don't want to allow adjacent devices to gain information about this router for security reasons.SolutionYou can disable CDP on a single interface by using the command no cdp enable interface configuration command: Router1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router1(config)#cdp runRouter1(config)#interface FastEthernet0/0 Router1(config-if)#no cdp enableRouter1(config-if)#end Router1#And you can disable all CDP on the router with the global configuration command, no cdp run: Router1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router1(config)#no cdp runRouter1(config)#end Router1#

Which protocol will be used and how will traffic between the Router1 LAN and Router5 LAN be routed through the network?
***EIGRP traffic will use the path Router1, Router3, Router4, Router5 because it has the best metric.
What summary address can Router2 advertise to Router1 to reach the three networks on Routers 3 4 and 5 without advertising any public address space or overlapping the networks on Router1?
172.16.0.0/13
What command is used to configure a router's host name to Tech-router?
hostname router1
What mechanism will prevent Router1 from advertising false routing information back to Router2?
**split horizon
What is the problem with the addressing used in the topology?
The subnetwork configured on the serial link between Router1 and Router2 overlaps with the subnetwork assigned to Ethernet0 of Router3.
Which two static routes could be configured on Router1 to enable Host A to reach network 172.16.0.0?
**ip route 172.16.0.0 255.255.0.0 S0/0** ip route 192.168.0.1 172.16.0.0 255.255.0.0 S0/1

Which protocol can be used by Router1 to determine the IP address of Router2 when they are directly connected and only layer 2 connectivity exist between them?
Answer = ARPMeaning of ARP - "Address Resolution Protocol", is used to map IP Network addresses to the hardware (Media Access Control sub layer) addresses used by the data link protocol. The ARP protocol operates between the network layer and the data link layer in the Open System Interconnection (OSI) model.
