CCNP ADVANCED LAB 1Single Site Network

Advanced LabsLab 1: Single Site Network

ObjectiveThis lab will allow you to develop your ability to combine multiple technologies to create a network

infrastructure that is typical of a small to medium-size enterprise with a single site. You will use

your knowledge of VLANs, Layer 2 switching, Layer 3 routing, and dynamic routing protocols to

build this infrastructure.

Simulated Network OverviewYou will be creating a network with one router, one switch, and four PC hosts. Two of the PC hosts

will be connected to one VLAN, and the other two PC hosts will be connected to a different VLAN.

The router will have a subinterface for each VLAN, and 802.1q trunking will be used to connect

each subinterface to the appropriate VLAN on the switch.

You will be able to combine and use skills learned in prior labs to build out this network.

Lab TopologyFor this lab, your network design will include the devices shown in the Topology diagram below.

Simulator. To access each of the devices from within the Simulator, select the device name from

the appropriate menu in the Simulator. For example, to access P1R1, click the eRouters button

and select P1R1 from the drop-down menu.

IP network addresses, they are no longer in the same VLAN. Although P1PC1 is now inthe same VLAN as P1PC2 and P1PC4, it has a different IP network address from P1PC2and P1PC4, so pings to those hosts also fail.

VLAN of which it is now a member; thus, it has no connectivity to hosts in its own, or anyother, VLAN.

all hosts in a VLAN with the same IP network addresses is good network design.

on the switch itself if the switch has Layer 3 capabilities. In this network, P1SW1 does

Layer 3 between VLANs.If the router had enough Ethernet ports, you could connect a separate Ethernet porta Layer 2 trunking protocol that is supported by both P1R1 and P1SW1. You are using802.1q trunking because the switch only supports 802.1q. By using Layer 2 trunking,

6. After P1PC1 is moved back into VLAN 20, pings from P1PC1 to all other PC hosts andsubinterfaces are successful. Pings from P1PC1 to hosts and interfaces in VLAN 20 are allsuccessful because all hosts and subinterfaces in the same VLAN have the same networkaddress. Pings to hosts and subinterfaces in different VLANs have different network

addresses and are forwarded to the default gateway for delivery via Layer 3 routing.
