Thanks for the patch! While not a problem of this patch, reading the nice subject of it spurs the desire for topic and/or tutorial type docs for this epic, and we could even update the OVN Gateway High Availability Plan document [2], but that is of course separate patches. 2: https://github.com/ovn-org/ovn/blob/main/Documentation/topics/high-availability.rst > ovn-nb.xml | 6 ++++++ > 1 file changed, 6 insertions(+) > > diff --git a/ovn-nb.xml b/ovn-nb.xml > index 9873ff5e7..584cda6db 100644 > --- a/ovn-nb.xml > +++ b/ovn-nb.xml > @@ -3752,6 +3752,12 @@ or > <code>BFD</code> (forwards UDP port 3784) > </li> > </ul> > + <p> > + Note that for BGP to work in "unnumbered mode" (automatic on-link > + peer discovery), Logical Router Port needs to enable sending of There are many references to RFCs in this document, does perhaps the "BGP unnumbered" high level description deserve some RFC references? > + periodic IPv6 Router Announcements (see the <ref > + column="ipv6_ra_configs" key="send_periodic"/>). > + </p> I believe we found some additional configuration required when enabling this downstream, such as ipv6_ra_configs:address_mode. The default values for ipv6_ra_configs:max_interval and ipv6_ra_configs:min_interval also do not work well with this feature, and need to be set for proper operation.
