[ovs-discuss] Forwarding between Multiple interfaces Openflow

[Aaron Rosen]

Hi Ben,

Sorry to bring this back up but for some reason I can't get this working
again and I was hoping someone would know why.


I have interface dp1 - 130.127.39.235 and interface dp0 - (No ip address
assigned).

When running tcpdump on dp1 I see packets like this:

IP 130.127.39.173 > 192.168.1.2: IP 130.127.39.173 > 192.168.1.3: ICMP echo
request, id 46093, seq 1561, length 64 (ipip-proto-4)

My routing tables are the following:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
192.168.20.20   192.168.2.3     255.255.255.255 UGH   2      0        0
wlan1
192.168.2.3     *               255.255.255.255 UH    2      0        0
wlan1
130.127.39.128  *               255.255.255.128 U     0      0        0 dp1
192.168.2.0     *               255.255.255.0   U     0      0        0
wlan1
192.168.1.0     *               255.255.255.0   U     0      0        0 dp0

Because of this I would expect to the the packet on dp0 but I don't (when
running tcpdump on dp0).


Any ideas why?

Thanks,

Aaron
