OpenStack gerrit 529833 0 None master: MERGED networking-ovn: Make use of native OVN IPv6 Router Advertisement support (I5d4d16e517d71830ea16245529dd2ba5433e0fd3) 2018-07-19 01:25:27 UTC

Description Numan Siddique 2017-10-03 15:16:20 UTC
Description of problem:

OVN presents doesn't send IPV6 periodic RA packets. Any logical router configured with "slaac" should support this.

Additional info:

Comment 1 Numan Siddique 2017-10-04 07:01:16 UTC
Description is wrong - IPv6 periodic RA should be sent irrespective of type of address mode configured on the logical router (i.e slaac, dhcpv6stateful/stateless).

Comment 4 Miguel Angel Ajo 2017-12-11 11:22:45 UTC
@Numans, do we have the counterpart for this on networking-ovn ?

Comment 5 Numan Siddique 2017-12-11 11:35:09 UTC
@Miguel - No. This needs work in networking-ovn

Comment 6 Numan Siddique 2017-12-11 11:35:10 UTC
@Miguel - No. This needs work in networking-ovn

Comment 10 Mark Michelson 2018-01-08 15:33:05 UTC
This has been merged into OVS now and will be available in the first release of OVS 2.9

Comment 14 Jon Schlueter 2018-06-27 17:23:05 UTC
According to our records, this should be resolved by openvswitch-2.9.0-19.el7fdp.1.  This build is available now.

Comment 16 Eran Kuris 2018-07-09 07:40:03 UTC
This RFE cannot be verified without the fix of https://bugzilla.redhat.com/show_bug.cgi?id=1567735

The fix referred in the previous comment landed already

I checked IPv6 connectivity check took tcpdump to see the RA packets
