The only way for SFC to work in OpenStack is to also use Netvirt. This
is because there needs to be a classifier in place that maps
subscriber/tenant traffic to service chains. Currently, the only
supported classifier is implemented in Netvirt.
For pure OpenFlow-based SFC, you just need to install these features:
opendaylight-user@root>feature:install odl-sfc-openflow-renderer
odl-sfc-ui odl-ovsdb-openstack
This will in-turn install the rest of the needed SFC features. Notice
the "odl-sfcofl2" feature is deprecated in Boron (still works though),
and has been removed in Carbon. Basically we just changed the name to
"odl-sfc-openflow-renderer".
Im not sure how well the "odl-l2switch-hosttracker" and
"odl-l2switch-arphandler" features will play with SFC due to the
aforementioned Application Coexistence issues. Netvirt will handle all
the tenant VM traffic for you.
I would recommend only installing SFC and Netvirt as listed above.
Dont forget to send the 2 Application Coexistence curl commands
mentioned previously.

Brady

Hi Brady,
We were configuring the “br-test” just to verify the functionality as
mentioned in the section *Verifying mapping from SFF to OVS* of Boron
User Guide
http://docs.opendaylight.org/en/stable-boron/user-guide/service-function-chaining.html
We are using “br-int” only as mentioned in SFF(sff6).
Initially, we had created the flows without Netvirt only. But didn’t
succeed, so thought of adding the Netvirt Functionality also.
We just want to create a Service chain (with only one SF) in Open
stack using ODL. For that purpose, we installed below mentioned
packages in ODL (using feature: install in karaf) but we are not
convinced that this is the right mix of packages required for the
service chain to work. Can you please share a bare minimum set of
packages that we need, to create a service chain in Open stack using ODL ?
oodl-ovsdb-openstack
oodl-dlux-core
oodl-dlux-all
oodl-sfc-ui
oodl-sfc-ovs
oodl-sfc-provider
oodl-sfc-model
oodl-sfc-ui
oodl-openflowplugin-nxm-extensions
oodl-openflowplugin-flow-services
oodl-l2switch-hosttracker
oodl-l2switch-arphandler
oodl-sfcofl2
oodl-netvirt-impl

*Subject:* Re: [sfc-dev] ODL SFF Creation Issue
Anirudh,
A few comments on your setup and attached configuration:
Why do you want to create "br-test"? Normally in an OpenStack env, the
SFF should be on the already created "br-int". I dont see anywhere in
the config any references to "br-test". The only configured SFF (sff6)
is being configured on "br-int".
From the flows you attached:
* There is no Netvirt classifier being configured, which is on table=11
* There are no SFC flows configured
If you plan to use both SFC and Netvirt on the same bridge, then the
Application Coexistence needs to be configured so that SFC and Netvirt
dont stomp on each other's flows. This consists of offsetting the SFC
flows to its own set of OpenFlow tables.
Here are the commands we usually use to configure Application
Coexistence for SFC and Netvirt. These commands must be sent before
creating any VMs.
curl -u admin:admin -H 'Content-type: application/json' -X PUT -d
{"netvirt-providers-config":{"table-offset":1}}
http://192.168.0.2:8181/restconf/config/netvirt-providers-config:netvirt-providers-config
curl -u admin:admin -H 'Content-type: application/json' -X PUT -d
'{"sfc-of-renderer-config":{"sfc-of-table-offset":"150","sfc-of-app-egress-table-offset":"11"}}'http://192.168.0.2:8181/restconf/config/sfc-of-renderer:sfc-of-renderer-config

Hi,
We have installed Openvswitch 2.5.90 with NSH patch and also
upgraded our ODL setup to distribution-karaf-0.5.0-Boron.
The following packages have been installed on it :-

Still we are facing following issues :-
oif a bridge(br-test) request is POST in the ODL from the Rest
Client, then corresponding SFF for this OVS Bridge should be
configured, which is not happening in our case.
oif a bridge(br-test) is created in Openstack using ovs-vsctl
command, then corresponding SFF for this OVS Bridge should be
configured, which is not happening in our case.
oAfter configuring the Rendered Service Path, we can observe the
flow drop at table 10.
Please find attached the following :-
oKaraf logs with a log level of DEBUG org.opendaylight.sfc

oSFF-SF-ACL-CLASSIFIER REST API
oOvs-vswitchd logs
We are kind of stuck in this issue, request you all to please
extend your support in order to resolve it.

*Subject:* ODL SFF Creation Issue
Hi,
We are using ODL Beryllium-SR4 release integrated with Openstack
Mitaka Release having OVS version 2.6.1 and trying to create SFF
by manually creating a bridge in the compute node.
The following packages are installed in ODL :-
·odl-ovsdb-openstack
·odl-dlux-core
·odl-dlux-all
·odl-sfc-ui
·odl-sfc-ovs
·odl-sfc-provider
·odl-sfc-model
·odl-sfc-ui
·odl-openflowplugin-nxm-extensions
·odl-openflowplugin-flow-services
·odl-l2switch-hosttracker
·odl-l2switch-arphandler
·odl-sfcofl2
As per the Beryllium User
Guidehttps://docs.google.com/viewer?a=v&pid=sites&srcid=ZGVmYXVsdGRvbWFpbnxpam5iZmVzY21hZWRhcHxneDoyM2VjNmZmNTg2N2RhMmFh
*, Chapter 25 Section Configuring SFC-OVS*, if a bridge(br-test)
request is POST in the ODL from the shell, then corresponding SFF
for this OVS Bridge should be configured.
But in our case this is not working.
The bridge details is reaching the ODL karaf.log(attached in the
mail), but SFF creation is not successful.
The same issue is being observed using Boron SR1 Release.
Can someone please help us in resolving the issue.
PFA the karaf.log with a log level of DEBUG org.opendaylight.sfc
