Attaching new interface to VM does not install flow in the OVS for the new interface

a. Create net1, net2
b. Net1- 111.111.111.0/24 , net2- 222.222.222.0/24
c. Both have their own default gw- 111.111.111.254 , 222.222.222.254
d. Add router interfaces
e. Add VM1 to net1 (111.111.111.2) and VM2 to net2 (222.222.222.2)
f. Ping works fine
g. Change default gw on net1 to 111.111.111.250
a. Need to delete the router interface, then change the gw in the network and then change it in the VM as well
h. Ping works fine
i. < here I played a bit with FIP- adding removing etc. worked fine>
j. Attach net1 interface to VM2 (111.111.111.3)
k. Add interface info in the VM-
i. sudo ip addr add 111.111.111.3/24 dev eth1
ii. sudo ip link set eth1 down
iii. sudo ip link set eth1 up
iv. verify route –n was added properly
l. Ping from VM2 to VM1  doesn’t work.
m. I see no rule for the new interface in table 50 or 51
