By manually adding nat-addresses=router for logical router type switch port
make it go further, above are not the problem now, thanks all.

Re: [ovs-discuss] OVN patch port for localnet can't be created

[Hui Xiang]

The ovn-trace target to vm floatingip is finally identified as MC_unknown
because there are only three lflows in the lswitch for public net, does it
correct for normal case, where should I look next?

lflow:
  table=15(ls_in_l2_lkup  ), priority=100  , match=(eth.mcast),
action=(outport = "_MC_flood"; output;)
  table=15(ls_in_l2_lkup  ), priority=50   , match=(eth.dst ==
fa:16:3e:2e:ea:e9 &&
is_chassis_resident("cr-lrp-640d0475-ff83-47b7-8a4d-9ea0e770fb24")),
action=(outport = "640d0475-ff83-47b7-8a4d-9ea0e770fb24"; output;)
  table=15(ls_in_l2_lkup  ), priority=0, match=(1), action=(outport
= "_MC_unknown"; output;)

Re: [ovs-discuss] OVN patch port for localnet can't be created

[Hui Xiang]

Thanks Ben.

After adding sbrec_port_binding_add_clause_type(, OVSDB_F_EQ,
"localnet"); in the update_sb_monitors() function, the patch ports for
localnet can be created,
but that is very confused when debugging the program, initially this
hypervisor is set as the gateway chassis where other vms spawned in other
hypervisor can go dnat_and_snat
through this node that without any vm spawned. In the begginging the patch
ports are created successfully, then I booted two vms, assigned
floatiingips, they are not recheable, so I begin to do ofproto/trace,
during that time, the patch ports suddenly deleted and can't be created
well. The GDB showed that no localnet type binding can be found from ovn sb
idl, I
am not quite understand the ovn sb idl update/monitor logistic so far.
Anyway probably my environment is messed up, I have re-create the
environment and try to do again.

Re: [ovs-discuss] OVN patch port for localnet can't be created

[Numan Siddique]

Is this openstack setup with networking-ovn ?

Can you run "ovn-nbctl list logical_router_port | grep redirect-chassis"
and make sure that networking-ovn has scheduled the gateway router port to
the desired chassis ?

May be the gateway router port is scheduled to some other chassis.

You can can run "ovn-nbctl set logical_router_port
options:redirect-chassis="CHASSIS_UUID_WHERE_YOU_WANT_TO_SCHEDULE" to
schedule it to your desired chassis.

Thanks
Numan

Seems it even doesn't get the "" type, just only patch and chassisredirect.

[ovs-discuss] OVN patch port for localnet can't be created

[Hui Xiang]

Hi folks,

  When I am running ovn in one of my node having the gateway port connected
external network via localnet, the patch port can't be created between
br-ex(set by ovn-bridge-mappings) with br-int, after gdb, it seems the
result get from SBREC_PORT_BINDING_FOR_EACH (binding, ctx->ovnsb_idl)
doesn't include 'localnet' binding type, however it does exist from
ovn-sbctl list port_binding, either I am missing any configuration to make
it work or this is a bug.

  Please have a look and thank much.
