Hi @sureshanaparti
Would you mind extracting the code at lines 1967-1972 to a specific method?
Then, it allows you to write test cases for the newly created method and proper
documentation of the method behaviors?

> ISSUE
> ==================
> If there are two public networks on two VLANs, and a pair redundant VRs
> acquire IPs from both, the associated NICs on the redundant VRs will have
> mismatching MAC addresses.
> The example below shows the eth2 NICs for the first public network
> (210.140.168.0/21) have matching MAC addresses (06:c4:b6:00:03:df) as
> expected, but the eth3 NICs for the second one (210.140.160.0/21) have
> mismatching MACs (02:00:50:e1:6c:cd versus 02:00:5a:e6:6c:d5).

> CloudStack should ensure that the NICs for all public networks have matching
> MACs.
> REPRO STEPS
> ==================
> 1) Set up redundant VR.
> 2) Set up multiple public networks on different VLANs.
> 3) Acquire IPs in the RVR network until the VRs get IPs in the different
> public networks.
> 4) Confirm the mismatching MAC addresses.
> EXPECTED BEHAVIOR
> ==================
> Redundant VRs have matching MACs for all public networks.
> ACTUAL BEHAVIOR
> ==================
> Redundant VRs have matching MACs only for the first public network.
