Not supported Li</li> <li>Added setting of C1/C2 in ExternalTable per destination</li> </ul> <p>This required a lot of pipeline work. The issue was that PolicyEnforcer is where we know about chains, but is still very "EPG/condition" centric, where a lot of the NSH header information is destination specific. Had to work on moving the final write of dest/source specific metadata, tunnelDests etc to the External pipeline which is all written from a new class ChainActionFlows.</p> <p>Asymmetric chain: Client’s packet to HTTP server gets chained, return path is not.<br/> <a href="https://gist.github.com/ffdd3b3053d3bb6e6bf1" class="external-link" target="_blank" rel="nofollow noopener">https://gist.github.com/ffdd3b3053d3bb6e6bf1</a></p> <p>So far tested:<br/> multiGBP classifier<br/> MultiSFF/SF <br/> multiEncap (VXLAN for ALLOW, VXLAN-GPE for CHAIN).<br/> All good, now working on <br/> symmetric chain (got a plan) <br/> coexistence i.e. GBP classifier + SFC SFF on same bridge/flowtable (got a plan).</p> <p><a href="https://git.opendaylight.org/gerrit/#/c/22539/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/22539/</a></p> Blocks GBP-58 Development External issue ID 3244 External issue URL ODL SR Target Milestone Priority Rank 0|i0352v:
