Two ways of writing the instructions of the scheme that settles a route by stacking them onto a packet are offered, one leaning on labels and one leaning on addresses. How many instructions does each carrier of the pair hold, and where do the addresses go once several of them are needed?

- One single label stands for one instruction while one address may hold an instruction or several of them at once, and the addresses go into the payload of the packet once more than one of them is needed to set out the path
- One single label stands for one instruction while one address may hold an instruction or several of them at once, and the addresses go into an extension header of IPv6 once more than one of them is needed to set out the path
- One label may hold an instruction or several of them at once while one address stands for one instruction alone, and the addresses go into an extension header of IPv6 once more than one of them is needed to set out the path
