Detailed Description

Packet steering into SR Policies.

This file is in charge of handling the FIB appropiatly to steer packets through SR Policies as defined in 'sr_policy_rewrite.c'. Notice that here we are only doing steering. SR policy application is done in sr_policy_rewrite.c

Supports:

  • Steering of IPv6 traffic Destination Address based
  • Steering of IPv4 traffic Destination Address based
  • Steering of L2 frames, interface based (sw interface)

Steer traffic L2 and L3 traffic through a given SR policy.

Parameters
is_del
bsidis the bindingSID of the SR Policy (alt to sr_policy_index)
sr_policyis the index of the SR Policy (alt to bsid)
table_idis the VRF where to install the FIB entry for the BSID
prefixis the IPv4/v6 address for L3 traffic type
mask_widthis the mask for L3 traffic type
sw_if_indexis the incoming interface for L2 traffic
traffic_typedescribes the type of traffic
Returns
0 if correct, else error
