Frr: FRR EVPN Without Creating VXLAN---Possible ?

[anspectrum]

Hi,
So far every implementation of EVPN on FRR platform is centric at VXLAN / VNI interfaces. EVPN does not necessarily have to be implemented along with VXLAN all the time.

Are there any future plans to incorporate plain layer-2 frame learning through BGP control plane?

[pguibert6WIND]

You seem to talk about ability to support mpls encapsulation, for instance ?
More than this, was your question including scalabilities concerns ( use an other method to encapsulate your packets - like ovs vxlan -) ?

as far as I know, there is on an old ticket a certain list of issues that have been listed regarding the work effort for leveraging mpls.

[anspectrum]

@pguibert6WIND, mpls encapsulation is already available with recent Linux kernels. I am not seeking any other encapsulating method as that will be Data Plane.
I am just curious about MAC Address learning through BGP control plane (EVPN) as other mainstream vendors have implemented it.

bump.

Hi,
sorry for delay,

• plain layer 2 = you mean some improved mechanism to tight layer2 with EVPN, like proxy ARP, GARP ?
  Having this , I think is the step +1 to reach with EVPN.

[anspectrum]

With plain layer 2, I meant like VPLS. Take from one Ethernet interface (not VXLAN interface) and transport it over to the other end. But unlike VPLS MAC learning be done using BGP (EVPN).
Simply speaking compliance to RFC 7432 (which does not talk about VXLAN).

[pguibert6WIND]

This said, I have a doubt on applying rfc7432 to VPLS.

You probably mean moving from VPLS architecture to RFC7432 architecture with BGP, ie BGP MPLS support for BGP EPVN.

Just to be sure it is part of feature request, and not maintenance issue.
This should be tracked in feature request page.

I'm working on EVPN-MPLS (RFC7432).

[Uttiponken]

@pjdruddy Do you have any status or timeline/roadmap for your implementation of RFC7432?

[pjdruddy]

@Uttiponken wotking on it now - would expect ho have PRs out in the next couple of months.
