Chapter 8 – Basic IP Routing
This chapter provides configuration background and examples for performing IP routing functions,
and includes the following topics:
• IP Routing Benefits, page 111
• Routing Between IP Subnets, page 111
• IP Subnet Routing Configuration, page 113
• Using VLANs to Segregate Broadcast Domains, page 115
• Defining IP Address Ranges for the Local Route Cache, page 117
• Dynamic Host Configuration Protocol, page 117
• Gratuitous ARP (GARP) Command, page 119
• Static Routes, page 119
IP Routing Benefits
Alteon uses a combination of configurable IP interfaces and IP routing options. The IP routing
capabilities provide the following benefits:
• Connects the server IP subnets to the rest of the backbone network.
• Performs Server Load Balancing (using both Layer 3 and Layer 4 in combination) to server
subnets that are separate from backbone subnets.
• Routing IP traffic between multiple Virtual Local Area Networks (VLANs) configured on Alteon.
Routing Between IP Subnets
The physical layout of most corporate networks has evolved over time. Classic hub and router
topologies have given way to faster switched topologies, particularly now that switches are
increasingly intelligent. Alteon is intelligent and fast enough to perform routing functions on a par
with wire speed Layer 2 switching.
The combination of faster routing and switching in a single Alteon provides another service—it
enables you to build versatile topologies that account for legacy configurations.
