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.
