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
bsid	is the bindingSID of the SR Policy (alt to sr_policy_index)
sr_policy	is the index of the SR Policy (alt to bsid)
table_id	is the VRF where to install the FIB entry for the BSID
prefix	is the IPv4/v6 address for L3 traffic type
mask_width	is the mask for L3 traffic type
sw_if_index	is the incoming interface for L2 traffic
traffic_type	describes the type of traffic

Returns

0 if correct, else error
