for IPsec tunnel endpoints.

	Tunneling means encapsulating data of one protocol type within

	another protocol and sending it over a channel that understands the

	encapsulating protocol. This can be used with xfrm mode tunnel to give

	the notion of a secure tunnel for IPSEC and then use routing protocol

	on top.
