Description of problem:
Using a setup with VLAN networks.
Launching instances connected each to a different network and both connected to
same router and the router also connected to an external network.
Connectivity to the FIP of each instance works.
There is no connectivity between the instances internal IPs.

When launching instances connected to each network on each compute node and the
removing the interfaces from the router and adding a them back - there is connectivity.

Version-Release number of selected component (if applicable):
opendaylight-6.2.0-4.el7ost.noarch

Steps to Reproduce:
1. Bring a setup with OpenDaylight and VLAN networks
2. Create an external network, two networks , a router.
3. Connect the router to each networks
4. Launch two instances , one connected to the first network and another to the
second network
