Hi everyone,

Thanks to those who joined our meeting yesterday!  For those who
couldn't make it or who wish to review what was discussed here's a link
to the meeting recording:

A summary of what was discussed and some follow up notes:

1. OVN 26.03 will be marked as LTS

2. EVPN support development updates and follow ups; Han brought up two
things:

a. L3 EVPN with ECMP routes that are configured in the kernel with
RTA_NH_ID (instead having explicit nexthop specification through
RTA_MULTIPATH/RTA_GATEWAY):
- on a closer look it seems that the OVS route parsing code in
route-table.c doesn't cover this use case
- we might have to add support for that in OVS and then combine it with
the nexthop tracking module that OVN supports on the main branch

b. vxlan’s underlay routes if they are also learned through BGP (can
also be ECMP); i.e., VTEP IP fdb entries with "dst" set to a nexthop
group instead of a single IP address:
- this is also not currently supported in OVN
- however, leveraging the nexthop tracking module in OVN should make it
possible to implement the missing support in the future

Han, would you happen to have time to look into these two new
development tasks?

3. Vladislav brought up a proposal to add OVN support to aggregate
announced routes.

4. Numan brought up a proposal for supporting OVN dynamic routing with
DVR (distributed routers with floating IPs).

5. I brought up a proposal for supporting "VRF-aware" logical routers
but upon discussion during the meeting, using Ilya's suggestion of
combining a new logical router with router policies that pkt.mark the
packets might provide everything we need already.  I'll investigate
further and discuss this with the users (ovn-k).

6. Matteo shared an update on his pending OVS series to expose the
peer_ifindex for Linux veths added as OVS interfaces.

Monday, June 22nd, 2026, 3PM UTC

Thanks again for joining!

Best regards,
