Hi, folks
Netfilter added a shifted port range mapping function in Linux kernel 4.19, it
looks like this:
iptables -t nat -A zone_wan_prerouting -p tcp -m tcp --dport 5000:5100 -j DNAT
--to-destination '192.168.1.2:2000-2100/5000'
5000-51000 is mapped to 2000-2100
Can ovs ct
Hi, folks
Recently we found some weird issues, ovs-vswitchd will crash occasionally when
ovs-ofctl add-br with protocol option if version of ovs command line tools in
neutron agent (which is packaged as k8s pod) is different from the one on the
host, or openflows in br-int can’t work as
Hi, folks
I’m changing Openstack Neutron to use openflow-based pipeline to implement
qrouter and floating IP, everything is ok when two VMs (which are in two
different compute nodes and two subnets but same network, so vlan tag is same),
but NORMAL action will drop packets if they are on
No, neighbor advertisement (reply for neighbor solicitation, i.e. ARP reply)
must have nd_options_type==2.

Out of curious, I remember OVN doesn't support OVS DPDK, I believe OVN also
does IPv6 ND by openflow, is it acceptable to use slow path to handle IPv6 ND
for OVS kernel datapath?

rnel datapath, per my check, kernel datapath with this patch can
work, I verified it by using openflow to do NS reply and ICMPv6 ping reply.
William, I guess you're using ovs userspace, so it doesn't have this issue.

Hi, folks
I need to set nd_options_type to 2 for NS message to respond IPv6 NS, my flow
is below, why nd_options_type can’t be set? Per commit
9b2b84973db76e1138d9234ff1b84bb6bb156011, it should work, what’s wrong?
Appreciate your help in advance, thank you.
$ sudo ovs-ofctl
Hi, folks
I noticed ping from local IP to remote IP of VXLAN port can’t work immediately
after OVS DPDK is started and VXLAN port is created, sometimes it needs to wait
for more than 1 minute, I found ARP request triggered by ping and ARP request
sent by ovs itself can’t be responded
Thanks Ben, I have registered myself by VPN, so it isn't an issue for me.

Thanks for your reply.

Look forward to getting your guide, is this default behavior of OVS? Can you

Flavio, this is an openstack environment, all the flows are added by neutron,
NORMAL action is default flow before neutron adds any flow, this is ovs default
flow.

Hi, all
We find ovs has serious performance issue, we only launch one VM in one
compute, and do iperf small udp pps performance test between these two VMs, we
can see about 18 pps (packets per second, -l 16), but
1) if we add 100 veth ports in br-int bridge, respectively, then the pps
/www.marriott.com), it can't show
this discount. Anyway I have booked it with this big discount rate, thanks a
lot, Aaron.
