			Overview
			The gated Routing Daemon
		• HELLO is designed to work with routers called Fuzzballs. Most
		installations use RIP or OSPF instead of HELLO. The HELLO
		protocol is no longer supported on HP-UX. You can use RIP or OSPF
		instead, because they are internal routing protocols.
		Do not mix RIP and OSPF protocols within a single network, because the
NOTE
		routing information may conﬂict.
		Table 1-1 compares the advantages and disadvantages of the RIP and

		OSPF protocols.
