Topology

Addressing Table

Background

This activity allows you to practice a variety of skills including configuring VLANs, PPP with CHAP, static and default routing, using IPv4 and IPv6. Due to the sheer number of graded elements, you can click Check Results and Assessment Items to see if you correctly entered a graded command. Use the cisco and class passwords to access privileged EXEC modes of the CLI for routers and switches.

Requirements

Addressing/

The addressing scheme uses the 192.168.1.0/24 address space. Additional address space is available between VLAN 15 and VLAN 1. VLAN 25 needs enough addresses for 50 hosts. Determine the subnet and complete the subnet table below.

Complete the Addressing Table by assigning the following addresses to VLAN 25:

R2 G0/0.25 – First IPv4 address

PC25 – 2nd IPv4 address

L25 – Last IPv4 address

Configure IPv4 addressing on the necessary end devices.

On R2, create and apply IPv4 and IPv6 addressing to the G0/0.25 subinterface.

VLANs

On S1, create VLAN 86 and name it BlackHole.

Configure S1 ports in static mode with the following requirements:

F0/1 is the native trunk for VLAN 99.

F0/7 – F0/18 as access ports in VLAN 15.

F0/19 – F0/24 as access ports in VLAN 25.

G0/1 – 2 and F0/2 – F0/6 are unused. They should be properly secured and assigned to the BlackHole VLAN.

On R2, configure inter-VLAN routing. VLAN 99 is the native VLAN.

PPP

Configure R1 and R2 to use PPP with CHAP for the shared link. The password for CHAP is cisco.

Routing

On R1, configure IPv4 and IPv6 default routes using the appropriate exit interface.

On R2, configure an IPv6 default route using the appropriate exit interface.

Configure IPv4 OSPF using the following requirements:

Use process ID 1.

Routers R1 and R2 are in area 0.

R1 uses router ID 1.1.1.1.

R2 uses router ID 2.2.2.2.

Advertise specific subnets.

On R1, propagate the IPv4 default route created.

Configure IPv6 OSPF using the following requirements:

Use process ID 1.

Routers R1 and R2 are in area 0.

Configure OSPF on appropriate interfaces on R1 and R2.

R1 uses router ID 1.1.1.1.

R2 uses router ID 2.2.2.2.

Connectivity

All devices should be able to ping the web server.
