Definition at line 179 of file sr_mpls_steering.c.

Here is the call graph for this function:

Here is the caller graph for this function:

int sr_mpls_policy_add	(	mpls_label_t	bsid,
		mpls_label_t *	segments,
		u8	behavior,
		u32	weight
	)

Create a new SR policy.

Parameters

bsid	is the bindingSID of the SR Policy
segments	is a vector of MPLS labels composing the segment list
behavior	is the behavior of the SR policy. (default//spray)
fib_table	is the VRF where to install the FIB entry for the BSID
weight	is the weight of this specific SID list

Returns

0 if correct, else error

Definition at line 152 of file sr_mpls_policy.c.

Here is the caller graph for this function:

int sr_mpls_policy_assign_endpoint_color	(	mpls_label_t	bsid,
		ip46_address_t *	endpoint,
		u8	endpoint_type,
		u32	color
	)

Update the Endpoint,Color tuple of an SR policy.

Parameters

bsid	is the bindingSID of the SR Policy
endpoint	represents the IP46 of the endpoint
color	represents the color (u32)

To reset to NULL use ~0 as parameters.

Returns

0 if correct, else error

Here is the caller graph for this function:

int sr_mpls_policy_del

(

mpls_label_t

bsid

)

Delete a SR policy.

Parameters

bsid	is the bindingSID of the SR Policy
index	is the index of the SR policy

Returns

0 if correct, else error

Definition at line 196 of file sr_mpls_policy.c.

Here is the call graph for this function:

Here is the caller graph for this function:

int sr_mpls_policy_mod	(	mpls_label_t	bsid,
		u8	operation,
		mpls_label_t *	segments,
		u32	sl_index,
		u32	weight
	)

Modify an existing SR policy.

The possible modifications are adding a new Segment List, modifying an existing Segment List (modify the weight only) and delete a given Segment List from the SR Policy.

Parameters

bsid	is the bindingSID of the SR Policy
fib_table	is the VRF where to install the FIB entry for the BSID
operation	is the operation to perform (among the top ones)
segments	is a vector of IPv6 address composing the segment list
sl_index	is the index of the Segment List to modify/delete
weight	is the weight of the sid list. optional.

Returns

0 ok, >0 index of SL, <0 error

		ip46_address_t *	next_hop,
		u8	nh_type,
		u32	color,
		char	co_bits,
		mpls_label_t	vpn_label
	)
