Objectives

Part $1$: Configure Basic Device Settings

Cable the network as shown in the topology,

Configure basic IP addressing for routers and PCs$.$

Configure OSPF routing.

Configure PC hosts.

Verify connectivity between hosts and routers.

Part $2$: Secure the Control Plane

Configure OSPF Authentication using SHA$256$

For authentication, use the password student$\_$ID

Verify OSPF Authentication

Background $/$ Scenario

The router is a critical component in any network. It controls the movement of data into and out of the network and between devices within the network. It is particularly important to protect network routers because the failure of a routing device could make sections of the network, or the entire network, inaccessible. Controlling access to routers and enabling reporting on routers is critical to network security and should be part of a comprehensive security policy.

Required Resources

$3$ Routers $($Cisco $4221$ with Cisco XE Release $16\mathrm{.}9\mathrm{.}6$ universal image or comparable with a Security Technology Package license$)$

$2$ Switches $($Cisco $2960+$ with Cisco IOS Release $15\mathrm{.}2(7)$ lanbasek$9$ image or comparable$)$

$2$ PCs $($Windows OS with a terminal emulation program, such as PuTTY or Tera Term installed$)$

Console cables to configure Cisco networking devices

Ethernet cables as shown in the topology

Instructions

Part $1$: Configure Basic Device Settings

In this part, set up the network topology and configure basic settings, such as interface IP addresses.

Step $1$: Cable the network.

Attach the devices, as shown in the topology diagram, and cable as necessary.
