SF selection algorithm shortest-path causes failure when creating RSP

Bug Verified Cannot Reproduce Keith Burns Brady Johnson Fri, 22 May 2015 11:05:43 +0000 Fri, 25 May 2018 17:43:24 +0000 Fri, 25 May 2018 17:43:15 +0000 unspecified Oxygen General 0 4 <p>The shortest path</p> <p>The shortest path algorithm needs you to build a complete SFs and SFFs netwrok topology, you should ensure every SFF has a correct SFF dictionary which includes SFFs it connects to. For your case, you should fill in SFF dictionary of two SFFS by json, REST APIs or SFC UI. This must be done manually.</p> <p>By the way, <a href="https://git.opendaylight.org/gerrit/#/c/19994/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/19994/</a> is part of future plan for automatic SFF-to-SFF connection build, it is a big picture we can consider in the future.</p> <p>So please fill in every SFF's SFF dictionary then retry.</p> <p>SFC UI for SFF dictionary</p> <p>Attachment ScreenHunter_01 May. 25 09.27.gif has been added with description: SFC UI for SFF dictionary</p> <p>Ahmed, please close this bug if this isn't an issue any more for you.</p> <p>This bug is marked for Lithium RC2 and has no owner. I'll take it for now so it stops hitting our screens as we look for bugs to fix.</p> <p>Can we confirm this is still an issue? Temp changing to Lithium-3</p> <p>Moving to Boron.</p> <p>I tested this in Fluorine, and it is no longer a problem. That is, its possible to create a 2-SF RSP as explained in the problem report with the SF Selection Algorithm set to ShortestPath, and there are no errors in the logs, and flows are pushed to the bridge as expected.</p> Development External issue ID 3338 External issue URL ODL SR Target Milestone Priority Rank 0|i02emf:
