Establishing a L2VPN Link to Our Rack

Last updated: July 18, 2017

Because of the complex nature of the CCIE Collaboration lab exam, it is nearly impossible to study for the exam without having physical phones sitting in front of you. We therefore highly recommend that you establish a Layer 2 VPN to INE for your studies.

This option requires you to provide hardware IP phones, a Cisco router, and a Cisco Catalyst switch at your location. Use one of the supported Cisco routers with an Enterprise IOS image installed, along with one of the supported Cisco Catalyst switches to extend each of your INE rented rack’s three sites’ Layer 2 switched networks to your IP phones and study computer at your study location.

Supported Cisco IOS Enterprise feature-set routers:

  • 2611XM (2611 non-XM will not support necessary L2TPv3)
  • 1841
  • 1941
  • 28xx
  • 29xx
  • 38xx
  • 39xx

Supported Cisco Catalyst switches:

  • 3550 (Inline power won't power 9971 phones, however CP-PWR-CUBE-4 can be used for 9971 phones)
  • 3560 (PoE preferable, however if non-poe 3560, CP-PWR-CUBE-3 can be used for 7962/65 and CP-PWR-CUBE-4 can be used for 9971 phones)
  • 3750 (PoE preferable, however if non-poe 3560, CP-PWR-CUBE-3 can be used for 7962/65 and CP-PWR-CUBE-4 can be used for 9971 phones)

Placement of your L2VPN Router

In order that we may provide you with a very simple sample configurations in the next sections that hopefully require very-little-to-no troubleshooting, we don't include anything like IOS firewall (CBAC/ZBF) or NAT in our sample configurations. It will therefore be necessary to place the L2VPN router that you choose to use, behind your own home cable/DSL modem and home router. Your home router should provide you with adequate firewall and NAT support, and you alone are solely responsible for setting this up and determining your own level of comfort and need with regard to security from the internets. We request that you simply place your L2VPN router behind your home router/firewall/NAT device, as well as allowing your own home mobile and fixed devices to also be placed behind your home router, thus giving the necessary internet access to both with no change to your current setup.

Sample Configurations

For instructions and sample configurations on setting up our Layer 2 Hardware VPN option, continue reading the topics in this section.

We do not provide any support for any home devices (laptops/desktops/iOS/Android/other) besides Cisco IP Phones that are connected to your L2VPN router or Cisco Catalyst switch. Also, any deviation from the sample configurations that are provided in the next two sections (except for EzVPN Group and Password changes and VLAN changes as we advise), will not be supported by INE.
