<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">An FDB entry for a Floating IP resource would only be required on nodes with ports attached to the related external network. Normally that means only the network nodes that are hosting virtual
routers attached to those external networks rather than compute nodes. However, there are less frequently used scenarios that involve customers launching VM instances directly on external networks and in those scenarios the external network will be instantiated
in some compute nodes as well as the network nodes. <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">In your test scenario, the external network will only be present on the network node and therefore only the agent running on the network node will be capable of processing any related FDB entries.
