Hi all:
I have been deploying OVN +ovsdpdk on openstack env these days, Now I have
an unresolved problem, under geneve type network,
the OVS topology is attached below. from the userspace-tunnel document, the
br-provider should have an ip address, but I have tried pinging between two
vteps across compute nodes(namely ping 10.142.18.247 -I br-provider), and ping
failed. I have found the br-provider on the other host received arp request but
not send arp reply out. So my question is: should the br-provider send an arp
reply when it gets arp request ? the br-provider is in ovs bridge which
datapath_type is netdev, so how can the kernel stack handle the arp request
received by br-provider ?
