<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">Thanks for your comments! An RFE has been written to upstream patch 88b7bc7. Before I submit the code, I think we should fix this bug. I think we can change the parameter “host” to “agent” in the
following lines:<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-CA" style="font-size:11.0pt">I agree, this is a bug. I think the only reason it hasn’t been an issue is because the only user of the get_fdb_entries RPC is the BGP agent and it is not passing a host in the request (it is
None), therefore it excludes the attempt to try and access the parameter as an agent based on the condition in _<i>create_agent</i>_fdb.<o:p></o:p></span></p>
