+Steering packets into a SR Policy
+=================================
+
+steer packets using the sr steering policy
+------------------------------------------
+
+To steer packets in Transit into an SR policy (T.Insert, T.Encaps and
+T.Encaps.L2 behaviors), the user needs to create an ‘sr steering
+policy’.
+
+::
+
+ sr steer l3 2001::/64 via index 1
+ sr steer l3 2001::/64 via bsid cafe::1
+ sr steer l3 2001::/64 via bsid cafe::1 fib-table 3
+ sr steer l3 10.0.0.0/16 via bsid cafe::1
+ sr steer l2 TenGE0/1/0 via bsid cafe::1
+
+Disclaimer: The T.Encaps.L2 will steer L2 frames into an SR Policy.
+Notice that creating an SR steering policy for L2 frames will actually
+automatically *put the interface into promiscous mode*.
+
+steer packets using the classifier
+----------------------------------
+
+Another way to steer packet is to use the classifier.
+
+First the user need to manually add the source routing node to the list
+of the ip6-inacl next nodes. Using the python api this can be done
+with:
+
+::
+
+ # jsonfiles = get list of json api files
+ vpp = VPP(jsonfiles)
+ vpp.add_node_next(node_name='ip6-inacl', next_name='sr-pl-rewrite-insert')
+
+Below is a classifier mask filtering all the packets from the interface
+TenGigabitEthernet5/0/0 on ip version and moving all ipv6 packets to the
+sr-pl-rewrite-insert node (dropping the others) and applying the source
+routing index 2. In essence, this means “apply this sr policy to all the
+packets from this interface)
+
+::
+
+ vpp# classify table miss-next 0 current-data-flag 1 mask hex f000000000000000 skip 0
+ vpp# classify session acl-hit-next 1 table-index 0 match hex 6000000000000000 action set-sr-policy-index 2
+ vpp# set interface input acl intfc TenGigabitEthernet5/0/0 ip6-table 0
