IP Routing Features

Overview of IP Routing

IP Interfaces

On the routing switches, IP addresses are associated with individual VLANs.

By default, there is a single VLAN (Default_VLAN) on the routing switch. In

that configuration, a single IP address serves as the management access

address for the entire device. If routing is enabled on the routing switch, the

IP address on the single VLAN also acts as the routing interface.

Each IP address on a routing switch must be in a different subnet. You can

have only one VLAN interface that is in a given subnet. For example, you can

configure IP addresses 192.168.1.1/24 and 192.168.2.1/24 on the same routing

switch, but you cannot configure 192.168.1.1/24 and 192.168.1.2/24 on the same

routing switch.

You can configure multiple IP addresses on the same VLAN.

The number of IP addresses you can configure on an individual VLAN interface

is 32.

You can use any of the IP addresses you configure on the routing switch for

Telnet, Web management, or SNMP access, as well as for routing.

Note All ProCurve devices support configuration and display of IP address in

classical subnet format (example: 192.168.1.1 255.255.255.0) and Classless

Interdomain Routing (CIDR) format (example: 192.168.1.1/24). You can use

either format when configuring IP address information. IP addresses are

displayed in classical subnet format only.

IP Tables and Caches

The following sections describe the IP tables and caches:

■ ARP cache table

■ IP route table

■ IP forwarding cache

The software enables you to display these tables.
