-# Steering packets into a SR Policy {#srv6_steering_doc}
-
-## steer packets uging 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 donne 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
