IP routing basics 
Hardware compatibility 
The HP 5500 SI Switch Series does not support configuring Layer 3 Ethernet interfaces.  
The HP 5500 SI Switch Series does not support VPN-related parameters.  
The HP 5500 SI Switch Series does not support OSPF , BGP, IS-IS, OSPFv3, IPv6 BGP, or IPv6 IS-IS. 
Overview 
IP routing directs the forwarding of IP packets on routers based on a routing table. This book focuses on 
unicast routing protocols. For more information about multicast routing protocols, see IP Multicast 
Configuration Guide . 
The term router in this chapter refers to both routers and Layer 3 switches. 
The types of interfaces that appear in any figures other than the network diagrams for configuration 
examples are for illustration only. Some of them might be unavailable on your switch. 
The term interface in the routing features refers to Layer 3 interfaces, including VLAN interfaces and 
route-mode (or Layer 3) Ethernet ports. You can set an  Ethernet port to operate in route mode by using the 
port  link-mode  route  command (see  Layer 2—LAN Switching Configuration Guide ).  
Routing table 
A router maintains at least two routing tables: one  global routing table and one forwarding information 
base (FIB). The FIB table contains only the optimal ro utes, and the global routing table contains all routes. 
The router uses the FIB table to forward packets. For more information about the FIB table, see  Layer 3—IP 
Services Configuration Guide . 
Routes can be classified by di fferent criteria, as shown in Tabl e  1. 
Table 1  Categories of routes 
Criterion Categories 
Destination  • Network route —Destination is a network. The subn et mask is less than 32 bits. 
• Host route —Destination is a host. The subnet mask is 32 bits. 
Whether the 
destination is directly 
connected • Direct route —Destination is directly connected. 
• Indirect route —Destination is indirectly connected. 
Origin 
• Direct route —A direct route is discovered by the data link protocol on an interface, 
and is also called an interface route. 
•  Static route —A static route is manually configured by an administrator. 
• Dynamic route —A dynamic route is dynamically discovered by a routing protocol.
