FIB_PATH_LIST_KEY_FLAGS

#define FIB_PATH_LIST_KEY_FLAGS   (FIB_PATH_LIST_FLAG_NO_URPF)

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

Enumeration Type Documentation

fib_path_list_attribute_t_

enum 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.
