Alioune,
networking-sfc resources not installed / not reachable , If installation
is okay, Possibly you may missed service_plugins entry in *neutron.conf *(
in case of manual networking-sfc installation)
it should be ,
*service_plugins =
neutron.services.l3_router.l3_router_plugin.L3RouterPlugin,networking_sfc.services.flowclassifier.plugin.FlowClassifierPlugin,networking_sfc.services.sfc.plugin.SfcPlugin*
*and restart q-svc services in screen -x *
*Thanks.,*
*Mohankumar.N *
