[ovs-discuss] [ovs-ovn 2.7] How to find the compute node hosting l3 gateway router

Hi Team,

I have done the installation of packstack pike using ovn as mechanism
driver on centos. I have one controller and two compute nodes.

- Created one tenant geneve based network (added as port to router) and a
flat external network (set as gateway for router).

[root at controller ~(keystone_admin)]# rpm -qa | awk '/openvswitch-ovn/
{print $1}'

I am trying to find a compute node on which my gateway router is hosted and
also the command to check the health of distributed logical routers.

It seems like that "lrp-get-gateway-chassis" command is not present in the
version which I am using.

[root at controller ~]# ovn-nbctl lrp-get-gateway-chassis
ovn-nbctl: unknown command 'lrp-get-gateway-chassis'; use --help for help

[root at controller ~]# ovn-nbctl --help | grep -i gateway


Output of ovn-nbctl show.
