◆ FIB_PATH_LIST_KEY_FLAGS

#define FIB_PATH_LIST_KEY_FLAGS   (FIB_PATH_LIST_FLAG_NO_URPF)

The flags on a path-list that contribute to its key in the DB.

So path-lists with these flags different are not conisdered the same.

Typedef Documentation

◆ fib_path_list_attribute_t

Enumeration of path-list flags.

◆ fib_path_list_flags_t

◆ fib_path_list_fwd_flags_t

Flags to control how the path-list returns forwarding information.

◆ fib_path_list_walk_fn_t

typedef fib_path_list_walk_rc_t(* fib_path_list_walk_fn_t) (fib_node_index_t pl_index, fib_node_index_t path_index, void *ctx)

Enumeration Type Documentation

◆ fib_path_list_attribute_t_

Enumeration of path-list flags.

Enumerator
FIB_PATH_LIST_ATTRIBUTE_FIRST 

Marker.

Add new flags after this one.

FIB_PATH_LIST_ATTRIBUTE_SHARED 

This path list is shareable.

Shareable path-lists are inserted into the path-list data-base. All path-list are inherently shareable, the reason we share some and not others is to limit the size of the path-list database. This DB must be searched for each route update.

FIB_PATH_LIST_ATTRIBUTE_DROP 

explicit drop path-list.

Used when the entry source needs to force a drop, despite the fact the path info is present.

FIB_PATH_LIST_ATTRIBUTE_LOCAL 

explicit local path-list.

FIB_PATH_LIST_ATTRIBUTE_EXCLUSIVE 

exclusive path-list.

Exclusive means the path will resolve via the exclusive (user provided) adj.

FIB_PATH_LIST_ATTRIBUTE_RESOLVED 

resolved path-list

FIB_PATH_LIST_ATTRIBUTE_LOOPED 

looped path-list.

one path looped implies the whole list is

FIB_PATH_LIST_ATTRIBUTE_POPULAR 

a popular path-ist is one that is shared amongst many entries.

Path list become popular as they gain more children, but they don't become unpopular as they lose them.

FIB_PATH_LIST_ATTRIBUTE_NO_URPF 

no uRPF - do not generate unicast RPF list for this path-list

FIB_PATH_LIST_ATTRIBUTE_LAST 

Marher.

Add new flags before this one, and then update it.
