Overview
The gated Routing Daemon
Chapter 1 25
• 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.
NOTE Do not mix RIP and OSPF protocols within a single network, because the
routing information may conflict.
Table 1-1 compares the advantages and disadvantages of the RIP and
OSPF protocols.
Table 1-1 Comparison of RIP and OSPF Protocols
RIP OSPF
Advantage: RIP is easy to
configure.
Disadvantage: OSPF is
complicated to configure and
requires network design and
planning.
Advantage: An end system (a
system with only one network
interface) can run RIP in passive
mode to listen for routing
information.
Disadvantage: OSPF does not
have a passive mode.
Disadvantage: RIP may be slow
to adjust for link failures.
Advantage: OSPF is quick to
adjust for link failures.
