Detailed Description

Packet steering into SR-MPLS Policies.

This file is in charge of handling the FIB appropiatly to steer packets through SR Policies as defined in 'sr_mpls_policy.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

int sr_mpls_steering_policy	(	int	is_del,
		mpls_label_t	bsid,
		u32	sr_policy_index,
		u32	table_id,
		ip46_address_t *	prefix,
		u32	mask_width,

	)

Steer traffic L3 traffic through a given SR-MPLS 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
traffic_type	describes the type of traffic

Returns

0 if correct, else error
