Hi all,
I have two OVS 2.8.0 switches on different ASes with this configuration:
*Topology:*
h1 (10.0.0.100) <--> (eth0) OVS1 (eth1) <--> (5.5.5.2) Router
(6.6.6.2) <--> (eth1) OVS2 (eth0) <--> (20.0.0.100) h2
*OVS1:*
Bridge "br0":
Port "br0"
Interface "br0"
type: internal
Port "eth0"
Interface "eth0"
Port "eth1"
Interface "eth1"
Port gre-int
Interface gre-int
type: gre
options: {remote_ip="6.6.6.1"}
Only br0 has IP assigned to 5.5.5.1. All the ARP requests are handled
from the controller and there is a default gateway to reach 6.6.6.1.
Also the flows are set correctly.
*OVS1:*
Bridge "br0":
Port "br0"
Interface "br0"
type: internal
Port "eth0"
Interface "eth0"
Port "eth1"
Interface "eth1"
Port gre-int
Interface gre-int
type: gre
options: {remote_ip="5.5.5.1"}
Same as OVS1.
So now when I am pinging from h1 to h2 the ICMP packet get encapsulated
from OVS1 and received at OVS2. OVS2 has the destination IP of the GRE
packet (on br0 interface) but it does not decapsulate it. Instead it
sends it as a packet in to the controller. Any idea why the GRE packet
is not getting decapsulated?
