router RIPng 'no network' command

[feba-code]

Hi!
We have frr versions 8.5 and 10.4 in use. In both cases, command 'no network X:X::X:X/M' in 'router ripng' section:

router ripng
  no network 12:1234:5678:abcd::/64
exit

seems to have no effect whatsoever and negated network keeps being announced.

Do you think it might have been fixed in some later version? Any hint in which one?

UPDATE. I figured it out that adding a line 'ripng_enable_apply_all(ripng);' to the function ripng_enable_network_delete () seems to fix it:

int ripng_enable_network_delete(struct ripng *ripng, struct prefix *p)
{
	struct agg_node *node;

	node = agg_node_lookup(ripng->enable_network, p);
	if (node) {
		node->info = NULL;
		agg_unlock_node(node);
		agg_unlock_node(node);
		ripng_enable_apply_all(ripng);
		return NB_OK;
	}
	return NB_ERR_INCONSISTENCY;
}
