Chapter 1 Routing Overview
1.1 Overview
1.1.1 Static Routing and Routing Protocols
I. Static routing
Static routing features zero overhead, simple configuration, and is applicable to simple
and stable networks. But it requires human intervention when the network topology
changes.
II. RIP
RIP is easy to configure and is insensitive to CPU and memory, so it is applicable to
small and medium sized networks. However, it converges slowly and cannot eliminate
route loops completely. In addition, periodic RIP updating multicasts or broadcasts
consume many network resources.
III. OSPF
OSPF is complicated to configure and requires high-performance CPU and memory. It
is applicable to medium and large sized networks. OSPF converges fast and can
eliminate route loops completely. It supports area partition and provides hierarchical
route management.
IV. IS-IS
IS-IS is complicated to configure and requires high-performance CPU and memory. It is
applicable to medium and large networks. ISIS converges fast and can eliminate route
loops completely. It supports area partition and provides hierarchical route
management.
V. BGP
BGP runs between ASs. Although complicated to configure, BGP features high
reliability, stability, and scalability, has flexible and powerful routing policies and
eliminates route loops completely.
1.1.2 Routing Protocols Supported by the H3C Low-End Ethernet Switches
The S7500 series switches support RIP, OSPF, IS-IS and BGP.
