Detailed Description

Set or delete a mapping from one NSH header to another and its egress (decap to inner packet, encap NSH with outer header)

Template Parameters
client_index- opaque cookie to identify the sender
context- sender context, to match reply w/ request
is_add- add address if non-zero, else delete
nsh_nsi- Key for nsh_header_t entry to map to. : 24bit NSP 8bit NSI
mapped_nsp_nsi- Key for nsh_header_t entry to map to. : 24bit NSP 8bit NSI this may be ~0 if next action is to decap to NSH next protocol Note the following heuristic:
  • if nsp_nsi == mapped_nsp_nsi then use-case is like SFC SFF
  • if nsp_nsi != mapped_nsp_nsi then use-case is like SFC SF Note: these are heuristics. Rules about NSI decrement are out of scope
sw_if_index- index number of outer encap for NSH egress
next_node- explicitly which node to send to Note the above parameters are instantiated by "encap-gre-intf <x>" means sw_if_index x, next_node gre-input
