Here you will find a range of virtual labs for use on both EVE-NG & GNS3.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.
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!
Cisco vIOS switches used as the CE devices and a LAG between them and the PE vMX’s. IS-IS for the underlay and LDP for the label distribution. You could use RSVP or Segment Routing if you prefer.

VPWS instance will now be up. OSPF has been configured on both CE devices and relatiionship is up
BGP is used between the CE & PE devices. Could use OSPF but would then need a sham link between CE devices to stop routes being shown as external routes.

OSPF has been configured on both CE devices and a neighbourship has formed confirming that the layer 2 circuit is up.
This topology is Option 3 utilising BGP-LU. IS-IS in the underlay and OSPF between the 2 CE Cisco devices. Can use other devices as CE’s if you prefer.

Your CE’s will now have a layer 2 circuit between them. In this example, OSPF has been configured on them and you can see from the routing tables that an adjacency has formed and they are learning each other’s routes.
Cisco vIOS routers used as the CE’s. It doesn’t appear that Arista has the ‘as-override’ command so you will need to use ‘allowas-in’ on the CE’s otherwise routes from the opposing CE will not be imported. This is due to the AS already being in the path and is standard BGP loop protection.
Loopbacks of 11.11.11.11 (ce1) & 12.12.12.12 (ce2) have been configured on the CE’s, redistributed into BGP and visible in the opposing CE’s route table.
OcNOS is an open network operating system produced by IP Infusion. A copy of the software to use with EVE-NG or GNS3 can be downloaded from their website (click below).
This lab is a simple L3VPN. IS-IS used as the underlay and iBGP between PE1 & PE2. If not familiar with OcNOS, the CLI is very similar to Cisco IOS but with a commit so don’t forget to issue that after you have applied the commands!

BGP is configured between the CE (Cisco vIOS) & PE devices and loopbacks have been configured on the CE’s with addresses of 22.22.22.22 & 33.33.33.33 respectively. These are being redistributed into BGP and you should now see the opposing loopback in the route table.

BGP is configured between the CE & PE devices and loopbacks have been configured on the CE’s with addresses of 111.111.111.111 & 222.222.222.222 respectively. These are being redistributed into BGP and you should now see the opposing loopback in the route table.
Aim of this lab is to create a layer 2 circuit between switch6 & switch7 and form an OSPF adjacency. IS-IS is used for the underlay as it’s better (it really is!).

Once all devices configured, run ‘show l2vpn evpn vc id 1‘ to confirm circuit is up and then configure OSPF on your CE devices (use whatever you prefer) and the adjacency will come up.
