<p class="MsoNormal"><span lang="EN-US">Hi, neutron stackers,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">My use case is as follows:<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US">1. create a router<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US">2. create a network with subnet 4.6.72.0/23<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US">3. attach the above subnet to the router<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US">4. update the router with route {destination: 4.6.72.0/23, nexthop: 4.6.72.10}, success<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US">5. remove the above route from the router, success<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US">6. update the router with the same route again, operation success, but the route isn't added to the router namespace, so not take effect<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US">This problem is caused by removing the connected route, so when adding the route the second time, "ip route replace" command fail.<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I think we need to restrict the modification of connected route.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I have reported a bug: <a href="https://bugs.launchpad.net/neutron/+bug/1339028">
https://bugs.launchpad.net/neutron/+bug/1339028</a><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Any thoughts?<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US"><o:p> </o:p></span></p>
