VPLS

Slightly different topology for this one as multi-homing and a bit of the good old Spanning Tree thrown in. Cisco vIOS routers and switches used for CE devices. EVE-NG import below.

BGP L2VPN

nick Leave a comment

Our first lab and to start we will go with a pretty straightforward BGP L2VPN.

The topology is 5 vEX devices. vEX2, Core & vEX4 act as route reflectors and IS-IS the IGP. Cisco vIOS routers are chosen as CE devices as they are pretty lightweight to run but you can change to the CE of your choice.

If using EVE-NG you can import the lab using the below file

Once all commands have been applied, run ‘show l2vpn connections‘ on vEX1 or vEX5 to confirm all is good. Example of output is below.

root> show l2vpn connections    
Layer-2 VPN connections:

Welcome to JNCIP-SP.

Here you will find a range of virtual labs for use on both EVE-NG & GNS3 to help with your certification studies. All the labs are provided free of charge and include all the commands to get the lab up and running. Also, lab templates will be provided for EVE-NG for you to import. If you are looking for labs from other vendors then please check lab-it-up.com.

The labs are all based on 3 different Junos virtual images. vJunos-switch & vJunosEvolved are free to download from Juniper’s website. vMX is now end of life and no longer available to download but sure some of you still have to image to use.

More labs will be added in due course so please check the site regularly for updates. In the meantime, happy labbing and good luck with your studies!
