IP routing configuration examples

This section provides configuration examples for common IP routing tasks using the Command Line Interface (CLI). For conceptual information about the IP routing topics covered in this section, refer to "An Introduction to IP Routing Protocols" (page 13).

Note: In many of the following configuration examples, a brouter port is used to create a connection to the network core. This practice does not imply that a brouter port is the only means through which a core connection can be established. The use of a brouter port is only one of many ways to create such a connection.

Address Resolution Protocol (ARP) configuration

The Nortel Ethernet Routing Switch 5500 Series provides the following Address Resolution Protocol (ARP) features:

•Default ARP aging

•Static ARP entries

•Proxy ARP

Static ARP entries can be used to solve the following instances encountered on many networks:

•To communicate with a device that does not respond to an ARP request.

•To prevent an existing ARP entry from aging out.

When a static ARP entry is configured, both the IP address and MAC address of a device is assigned to a physical port. This includes the VLAN number if the physical port is associated with a VLAN.
