  • 1.  VXLAN Configuration On EX4400

    Posted 08-18-2023 13:23

    Hello
    I need to configure VXLAN between 2 EX-4400 switches to extend several vlans between three(3) sites (Surco, Ica and San Borja, see figure bellow) interconnected by L3 layer links provided by a service provider (ISP), has anyone ever configured this scenario? And what considerations should I take into account?

    If it is not possible to apply VXLAN, what other solution could I implement?

    I hope can Iget your help.

    Best regards...

    Hello 

    If you have the right licenses on your switches you can easily run this 
    I have a similar scenario running at my place and it works but I use QFX switches for it

    Hello Grzegorz, 

    Have you any documentation with an example of VXLAN Configuration?

    Best regards

    Here, you will find an example where they use two VLANs doing what you want:

    https://www.juniper.net/documentation/us/en/software/junos/evpn-vxlan/topics/topic-map/vxlan-static.html#id-configuring-static-vxlan

    I haven't tried it, but it is usually OK with these examples. Just remember to have proper routing of the lo0 IP addresses between the sites if you use the example's lo0 vtep-source-interface (recommended).

    Well, according to this document, EX4400 supports EVPN VXLAN - 

    https://www.juniper.net/documentation/us/en/software/junos/evpn-vxlan/topics/concept/vxlan-constraints-qfx-series.html

    Depending on the version, should be fairly easy to implement it.

    As long as there is reachability between loopbacks of switches (static routing, dynamic, no difference), then you could build BGP EVPN peering between switches over loopback interface and then configure EVPN VXLAN itself.

    Below document may be useful, thus, it is for QFX. Putting those VLANs (stretched between data centers) into a routing-instance is not mandatory and related configuration can be done in global (default switch) instance.
