Typedef Documentation

◆ abf_policy_t

typedef struct abf_policy_t_ abf_policy_t

An ACL based Forwarding 'policy'.

This comprises the ACL index to match against and the forwarding path to take if the match is successful.

ABF policies are then 'attached' to interfaces. An input feature will run through the list of policies a match will divert the packet, if all miss then we continues down the interface's feature arc

◆ abf_policy_walk_cb_t

typedef int(* abf_policy_walk_cb_t) (index_t index, void *ctx)

Callback function invoked during a walk of all policies.

Definition at line 102 of file abf_policy.h.

Function Documentation

◆ abf_policy_delete()

const fib_route_path_t rpaths 
)

Delete paths from an ABF Policy.

If no more paths exist, the policy is deleted.

Parameters
