VTP Configuration Sim

Question

[am4show have=’p2;’]A new switch is being added to our LAN. Complete the following steps:
+ Configuring the building_2 switch with an IP address and default gateway.
+ Use the last available IP address on the management subnet for the switch host address.
+ In addition, the switch needs to be configured to be in the same VTP domain as the building_1 switch and also needs to be configured as a VTP client.
+ Assume that the IP configuration and VTP configuration on building_1 are complete and correct.

The configuration of the router is not accessible for this exercise. You must accomplish the following tasks:

Determine and configure the IP host address of the new switch.
Determine and configure the default gateway of the new switch.
Determine and configure the correct VTP domain name for the new switch.
Configure the new switch as a VTP client.

Note: You might be asked to use first, second… available IP address on the management subnet.[/am4show]

Nat Sim

Question

A network associate is configuring a router for the TUT company to provide internet access. The ISP has provided the company six public IP addresses of 198.18.184.105 198.18.184.110. The company has 14 hosts that need to access the internet simultaneously. The hosts in the company LAN have been assigned private space addresses in the range of 192.168.100.17 – 192.168.100.30.

The following have already been configured on the router:

– The basic router configuration
– The appropriate interfaces have been configured for NAT inside and NAT outside
– The appropriate static routes have also been configured (since the company will be a stub network, no routing protocol will be required.)
– All passwords have been temporarily set to “cisco”

Tasks:
+ Use NAT to provide Internet access to all hosts in the company LAN.
+ Name the router TUT
+ Inside global addresses: 198.18.184.105 198.18.184.110/29
+ Inside local addresses: 192.168.100.17 – 192.168.100.30/28
+ Numer of inside hosts: 14

OSPF Sim

June 23rd, 2018 320 comments

Question

9tut.net company has decided to network three locations to improve efficiency in inventory control. The routers have been named to reflect the location: Boston, Frankfurt, Lancaster.

OSPFSim

The necessary networking has been completed at each location, and the routers have been configured with single area OSPF as the routing protocol. The Boston router was recently installed but connectivity is not complete because of incomplete routing tables. Identify and correct any problem you see in the configuration.

Note: The OSPF process must be configured to allow interfaces in specific subnets to participate in the routing process.
