Hi, I see some discussion on ovs + gre but not sure what the solution is. I am facing some what similar issue w.r.t configuration and flow matching.
On host-1, gre0 interface is configured via ovs-vsctl add-br br0 ovs-vsctl add-port br0 eth0 ovs-vsctl add-port br0 gre0 -- set interface gre0 type=gre options:remote_ip=10.0.0.7 ifconfig eth0 0 ifconfig br0 10.0.0.3 netmask 255.255.255.0 up gre0 is added to br0 port table and I have verified using ovs-[vs/dp/of]ctl show commands however, gre0 interface is not in the interface table i.e. if I do "ifconfig -a" I don't see gre interface. Now, I configure flows for transmit and receive packets via gre0 tunnel as follows on host-1: ovs-ofctl add-flow br0 priority=104,idle_timeout=50000,dl_type=0x0800,nw_proto=1,nw_src=10.0.0.3/32,nw_dst=10.0.0.7/32,actions=mod_vlan_vid:300,mod_vlan_pcp:3,set_tunnel:111,2 ovs-ofctl add-flow br0 priority=104,idle_timeout=50000,tun_id=222,dl_vlan=200,actions=strip_vlan,NORMAL on host-2: ovs-vsctl add-br br0 ovs-vsctl add-port br0 eth0 ovs-vsctl add-port br0 gre0 -- set interface gre0 type=gre options:remote_ip=10.0.0.3 ifconfig eth0 0 ifconfig br0 10.0.0.7 netmask 255.255.255.0 up ovs-ofctl add-flow br0 priority=104,idle_timeout=50000,dl_type=0x0800,nw_proto=1,nw_src=10.0.0.7/32,nw_dst=10.0.0.3/32,actions=mod_vlan_vid:200,mod_vlan_pcp:3,set_tunnel:222,2 ovs-ofctl add-flow br0 priority=104,idle_timeout=50000,tun_id=111,dl_vlan=300,actions=strip_vlan,NORMAL When I ping from host-1 to host-2, on host-1, i see ICMP packets matching first entry, however, I am not able to capture packets going out since tcpdump won't work due to gre0 not in interface table. on host-2, packets are not matched at all. My question is, any additional configuration needed to get icmp packets go through tunnel interface?
