   VRs

   ##### CONFIGURATION
   <!--
   Information about the configuration if relevant, e.g. basic network, advanced networking, etc.  N/A otherwise
   -->
   XenServer 6.5, Advanced Networking
   
   ##### OS / ENVIRONMENT
   <!--
   Information about the environment if relevant, N/A otherwise
   -->
   N/A
   
   ##### SUMMARY
   <!-- Explain the problem/feature briefly -->
   When an advanced network has multiple public interfaces, the second (and subsequent) interfaces do not have the same MAC address on both VRs.  This means that after a failover, connectivity with the IPs on the second+ ranges is interrupted until the ARP entry times out.
   
   ##### STEPS TO REPRODUCE
   <!--
   For bugs, show exactly how to reproduce the problem, using a minimal test-case. Use Screenshots if accurate.
   
   For new features, show how the feature would be used.
   -->
   1.  Create zone with 2 or more public IP ranges
   2.  Create an advanced network, allocate IPs until you get IPs from both networks (or use the database to assign a specific IP)
   3.  Create a VM and assign a Static NAT IP to the IP from the second range
   4.  Log into both VRs, compare the MAC addresses of eth2 and eth3 on both VRs
   
   <!-- You can also paste gist.github.com links for larger files -->
   
   ##### EXPECTED RESULTS
   <!-- What did you expect to happen when running the steps above? -->
   
   ~~~
   MAC addresses for eth3 should be the same on both VRs
   ~~~
   
   ##### ACTUAL RESULTS
   <!-- What actually happened? -->
   
   <!-- Paste verbatim command output between quotes below -->
   ~~~
   MAC addresses for eth3 are different.
