IP Routing Features 
Overview of IP Routing 
Overview of IP Routing 
The HP Procurve Series 5300xl, 3400cl, and 6400cl switches offer the following 
IP routing features: 
■  IP Static Routes – up to 256 static routes 
■  RIP (Router Information Protocol) – supports RIP Version 1, Version 1 
compatible with Version 2 (default), and Version 2 
■  OSPF (Open Shortest Path First) – the standard routing protocol for 
handling larger routed networks 
■  IRDP (ICMP Router Discovery Protocol) – advertises the IP addresses of 
the routing interfaces on this switch to directly attached host systems 
■  DHCP Relay – allows you to extend the service range of your DHCP 
server beyond its single local network segment 
■  Downstream Host Support – varies for different switch models. The 
switches covered by this guide, when configured for IP routing, support 
the number of hosts indicated below: 
Switch Model  Downstream  Network Subnet 
Hosts  Addresses 
5300xl Chassis (Total)  192,000  n/a 
5300xl Chassis (Per Module)  128,000  n/a 
3400cl and 6400cl Stackables  8,000  1,000 
Throughout this chapter, the 5300xl, 3400cl, and 6400cl switches are referred 
to as “routing switches”. When IP routing is enabled on your switch, it behaves 
just like any other IP router. 
Basic IP routing configuration consists of adding IP addresses, enabling IP 
routing, and, enabling a route exchange protocol, such as Routing Information 
Protocol (RIP). 
For configuring the IP addresses, refer to the chapter titled “Configuring IP 
Addresses” in the Management and Configuration Guide for your switch. 
The rest of this chapter describes IP routing and how to configure it in more 
detail. Use the information in this chapter if you need to change some of the 
IP parameters from their default values or you want to view configuration 
information or statistics.
