Currently we are running JunOS 20.4R3 on our EVPN switches in Eqiad rows E and F.
~~We have one identified bug on 20.4There are several improvements and bugfixes in more recent releases that we need to upgrade to overcome, detailed in T306421, by which routed VXLAN overlay packets (i.e. those using a L3VNI tied to a routing instance rather than L2VNI tied directly to a Vlan) are dropped unless there is an IRB interface on the local system in an "up" state.~~T358488 and T365204, as well as some security fixes. So we need to upgrade the devices in these rows over the next while.
~~As soon as we've one server connected to a switch this condition is met, and things work as expected. Previously Juniper stated this was normal behaviour, after a lengthy TAC case, but it seems this limitation does not apply to 22.2 which we are using in codfw. ~~Current schedule proposed as follows:

I've itemized the hosts from each rack in the below sheet. I'll create individual tasks for each and add to the above when ready also.

We are running version 22.2 on the EVPN switches in codfw. We initially thought the above bug was fixed in that version but it seems it is still present. Nevertheless we should upgrade the Eqiad devices to keep everything on the same version.
