Function Documentation

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

int sr_mpls_policy_del	(	mpls_label_t	bsid,
		u32	index
	)

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 176 of file sr_mpls_policy.c.

Here is the caller graph for this function:

int sr_mpls_policy_mod	(	mpls_label_t	bsid,
		u32	index,
		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
index	is the index 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 if correct, else error
