previously garps/rarps where only sent for "external" lsp's if these had an ipv4 address attached. For lsp's on gateway routers that do not have an ipv4 address assigned (e.g. if they are ipv6 only) no rarps were send out.
This causes traffic outages when changing the priority of a gateway chassis as the phyiscal switches to not get the information where the mac address now resides. To fix this we send out rarps with just the mac address of the interface and no ip address. This change has been tested in an environment with 600 logical routers on a single ipv6 external network. Additionally we fix the issue that self-created rarp's are flooded to logical routers even if this is unnecessary (causing ovs to potentially drop the packet because of too many resubmits). This change is also available as a PR at https://github.com/ovn-org/ovn/pull/157 Felix Huettner (4): logical-fields: add rarp fields northd: handle own rarps like garps ovn-macros: support ipv6 in ovn_attach pinctrl: Send RARPs for external ipv6 interfaces controller/pinctrl.c | 23 +++++++++ lib/logical-fields.c | 8 ++++ lib/ovn-util.c | 2 +- northd/northd.c | 9 ++-- northd/ovn_northd.dl | 2 +- ovn-sb.xml | 2 + tests/ovn-macros.at | 9 ++-- tests/ovn-northd.at | 18 +++---- tests/ovn.at | 110 ++++++++++++++++++++++++++++++++++++------- 9 files changed, 148 insertions(+), 35 deletions(-) -- 2.38.0 Diese E Mail enthält möglicherweise vertrauliche Inhalte und ist nur für die Verwertung durch den vorgesehenen Empfänger bestimmt.
