A router supports redirection of IPv4 or IPv6 traffic arriving on a Layer 3 interface to a different routing instance (GRT or VRF) and next-hop IP at the same time. An OF controller can rely on this functionality and program PBR steering action for H-OFS instances with the switch-defined-cookie command enabled using the following OF encoding:
ALU_IPD_EXPERIMENT_ID:0X000025BA
ALU_AXN_REDIRECT_TO_NEXTHOP:2
flow_mod:
Instruction 1:
instruction=OFPIT_WRITE_ACTION/OFPIT_APPLY_ACTION
action=OFPAT_EXPERIMENTER(ALU_AXN_REDIRECT_TO_NEXTHOP),
Encoding as described in the Redirect to IP next-hop section (indirect flag must be set).
Instruction 2:
instruction type: OFPIT_WRITE_ACTIONS/OFPIT_APPLY_ACTION,
action type: OFPAT_OUTPUT,
port= SR OS LOGICAL port encoding GRT or VPRN Service ID as described in the SR OS H-OFS logical port section.
