<p class="MsoNormal"><span style="font-size:11.0pt" lang="EN-US">We
are currently working with OVS in order to be capable of
routing traffic through different interfaces connecting to
the internet. In order to maintain private ip addressing we
are using gre tunnel OVS implementation. However, we are
incapable of binding GRE tunnels to specific network
interfaces, where tunneled traffic should be forwarded and
finally egress. Once traffic egress the gre Openflow port in
the OVS, it seems it uses Linux routing table to forward the
traffic to the corresponding network interface. Under this
situation, we are incapable of using gre ports in OVS to
load balance traffic matched in the OVS to different
interfaces, as traffic will normally use the single default
route in Linux routing table.<o:p></o:p></span></p>

Questions like these come up often and I always try to remind and/or
inform people that IP addresses in<br>
Linux belong to the system, not interfaces. Same goes for the
routing table. Using gre ports to do load<br>
balancing is something I've never heard of.<br>
