<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">The primary reason for this patch is to be able to export the FIP address information via BGP eVPN. Our BGP eVPN extensions make use of the L2POP framework to export MAC/IP information and
this patch ensures that the FIP addresses are included in the exported information.

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">In addition to the BGP eVPN functionality, this patch also avoids broadcast for scenarios when two VM instances, residing on different networks, communicate via their respective FIP addresses.
