Juniper vMX – Inter-AS BGP L2VPN Option B

10 November 202410 November 2024 nick Leave a comment

Slight difference to Option A topology. Still running Segment Routing in AS65200 but AS65400 is now running RSVP. Great article linked below from Chris Parker who explains Option B in more detail (click on Network Fun Times link). OSPF configured on the 2 Cisco CE devices.

Juniper vMX – Inter-AS L3VPN Option A

10 November 202410 November 2024 nick Leave a comment

This topology uses option A and, as usual, 2 Cisco devices as CEs. BGP is used for routing between PEs & CEs. AS65200 is running Segment Routing and AS65400 LDP.

The 2 CE devices will now have IP connectivity and you can see the respective routes have been learnt on both sides.

Juniper vMX – Carrier of Carriers EVPN VPLS

9 November 202410 November 2024 nick Leave a comment

This lab is slightly different to the other Carrier of Carrier lab where LDP was used in each AS. In this lab, AS65200 is using LDP, AS65400 RSVP & AS65600 Segment Routing. 2 Cisco vIOS devices used as CE devices

Juniper vMX – IPv6 Tunneling over SR

3 November 20243 November 2024 nick Leave a comment

Quite a simple lab this one. A customer wants to establish IPv6 connectivity between 2 sites over our SR IPv4 core so IPv6 tunneling is required. 2 Cisco vIOS routers used as the CE devices.

Juniper vMX – EVPN VPWS

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.

Juniper vMX – Segment Routing L3VPN

You will need a trial license from Juniper for this lab, which can be obtained from the below URL.

https://www.juniper.net/gb/en/dm/vmx-trial-download.html

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.

The L3VPN will now be up and the CE devices receiving routes from each other. You may need to reboot the vMX devices before you see the routes.

Establish a layer 2 circuit between the 2 CE devices, traversing 3 separate AS’s.

This topology is Option C 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.

Juniper vJunosEvolved – L3VPN

An example Juniper L3VPN configuration example. IS-IS underlay and BGP between PE’s & CE’s.

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.
