My bad, I misread man pages and I was debugging tunnel config problem
so thought probably local_ip can be used to influence soure_ip in the
linux and could solve my config problem and from the output of
ovs-vsctl assumed ip addresses are configured correctly. Output from
ovs-vsctl shows as follows.
ovs-vsctl shows
963b4cf-f4b9-4852-b816-807340662889
Bridge "br0"
Port "gre0"
Interface "gre0"
type: gre
options: {local_ip="10.0.0.3,remote_ip=10.0.0.7"}
Port "eth0"
Interface "eth0"
Port "br0"
Interface "br0"
type: internal
For the flow configuration, I think I need to have couple of flows
configured via ovs-ofctl i.e.
On transmit side:
1. match IP/ICMP/IP_src/IP_dst and actions=2(gre0 port number)
2. match IP/GRE/IP_src/IP_dst and actions=1(eth0 port number)
On receive side:
1. match IP/GRE/IP_src/IP_dst and actions=??? to strip/decap gre header
2. match IP/ICMP/IP_src/IP_dst and actions=NORMAL
Thanks,
Ravi
