Lab Topology


Lab Device Requirements

Lab devices are part of the topology and users can interact with them either directly through the console or network.

Hardware compatibility with NETLAB+ does not guarantee the compatibility of labs. Please check the Academy curriculum, NDG pod guides, and lab support pages for specific hardware and IOS requirements.

The Advanced Router Pod contains three routers, R1, R2 and R3.

Other equipment may work if it is supported by NETLAB+ and can meet the minimum requirements for feature sets, interfaces, IOS, RAM, and Flash

Devices Ethernet Serial BRI PRI AUX/External Modem
R1 1 2 1 1
R2 1 1 Optional 1 (Recommended) Optional
R3 1 2 1 1

Router Interfaces

The NETLAB+ interface name translation feature is supported on this pod type. This may influence the selection of modular interface cards and slot placement within the router. Please review the expected interface names for each router.

The Ethernet interface must be a built-in interface, which is capable of activation from the ROM monitor mode. All NETLAB+ supported routers have at least one Ethernet interface that meets this requirement.

Serial interfaces may be built-in, or provided by modular interface cards such as the WIC-2AS or WIC-2T. Serial connections between routers require the appropriate serial cables. You can use DTE and DCE cables back-to-back, or special cables that provide both DTE and DCE in one cable (available from SIGMAnet).

Be sure to match your router and Adtran Atlas BRI and PRI interface types according to you local requirements (i.e. BRI vs. S/T, T1/PRI vs. E1/PRA).

R1 and R3 communicate with the PSTN using external modems (sold separately).

Adtran Atlas 550 Setup

The Advanced Router Pod utilizes an Adtran Atlas 550 to emulate functions normally obtained from a network service provider. The Atlas 550 is statically configured and always powered on. Lab users do not interact with the Atlas management console.

Slot Configuration

Per the following table, insert the following cards into following Atlas 550 chassis slots.

Slot Module
SLOT 1 Dual Nx56/64 V.35 Module
SLOT 2 Dual Nx56/64 V.35 Module
SLOT 3 FXS Module
SLOT 4 ISDN BRI Module or S/T Module (as required)
Serial and PVC Setup

Per the following table, connect the router serial interfaces to the Atlas 550 and create 6 permanent virtual circuits using the Atlas management interface.

Router Local
Local DLCI Adtran Adtran Maps to Remote
R1 Serial 0/0 102 1/1 1/2 R2 Serial 0/0
R1 Serial 0/0 103 1/1 2/1 R3 Serial 0/0
R2 Serial 0/0 201 1/2 1/1 R1 Serial 0/0
R2 Serial 0/0 203 1/2 2/1 R3 Serial 0/0
R3 Serial 0/0 301 2/1 1/1 R1 Serial 0/0
R3 Serial 0/0 302 2/1 1/2 R2 Serial 0/0
FXS Setup

Using the following table, connect R1 and R3 to external modems, and configure the phone numbers on the Atlas 550. R2 may be optionally connected to the third FXS port.

Router Port Atlas 550(FXS) Phone Number
R1 AUX 3/1 5556001
R3 AUX 3/2 5556002
R2 (Optional) AUX 3/3 5556003
BRI Setup

Per the following table, connect your router BRI (or S/T> interfaces to the Atlas 550.

Router Port Atlas 550(BRI) SPID
R1 BRI 4/1 SPID1: 51055510000001 5551000
SPID2: 51055510010001 5551001
R3 BRI 4/2 SPID1: 51055520000001 5552000
SPID2: 51055520010001 5552001
R2 (Optional) BRI 4/3 SPID1: 51055530000001 5553000
SPID2: 51055530010001 5553001
PRI Setup

To implement PRI, connect router R2's PRI interface to the Atlas 550 PRI interface.

Control Device Requirements

Control devices provide internal connectivity, console access, and managed power. Control devices are dynamically managed by NETLAB+ and are not accessible or configurable by end users.

  • Control switches provide connectivity between devices in the pod.
  • Access server lines provide console connections to lab equipment.
  • Switched outlets provide managed electrical power, allowing NETLAB+ and users to turn lab equipment on and off.
Control Device Requirements for the Advanced Router Pod
Control Device Resource Quantity Required
Control Switch 3 Consecutive Ports
Access Server 3 Lines
Switched Outlet Devices 3 Outlets
The Advanced Router Pod requires 3 consecutive ports on a control switch.

The Advanced Router Pod requires 3 async ports on an access server.

The Advanced Router Pod requires 3 outlets on a switched outlet device.
