Re: using vlan tagged ports in cluster

 

Hi, JR,

You should check your route. Before "ovs-vsctl add-port br-ex p1p1.4", you
should have the route entry like:
192.168.251.0   0.0.0.0  255.255.255.0 U 0 0 0 p1p1.4
But after that, since p1p1.4 is plugged in br-ex, you should change the
above route to go through br-ex, and may also change other (default route)
to this interface as well, if they originally go through p1p1.4.

Regards,
Rain
