Introduction
This chapter describes the route selection process used by the AlliedWare Plus
TM
Operating System. Understanding the route selection process helps in analyzing and
troubleshooting route-related problems.
The process of routing packets consists of selectively forwarding data packets from one
network to another. Your device must determine which network to send each packet to,
and over which interface to send the packet in order to reach the desired network. This
information is contained in your device routes. For each packet, your device chooses the
best route it has for that packet and uses that route to forward the packet. In addition, you
can define filters to restrict the way packets are sent.
Types of Routes
Your device learns routes from static information entered as part of the configuration
process and by listening to any configured routing protocols. The following types of
routes are available on your device:
Interface Routes
Your device creates an interface route when you create the interface. This route tells your
device to send packets over that interface when the packets are addressed to the
interface’s subnet.
Static Routes
You can manually enter routes, which are then called static routes. You can use static
routes to:
■ specify the default route (to 0.0.0.0). If your device does not have a route to the
packet’s destination, it sends it out the default route. The default route normally
points to an external network such as the Internet.
■ set up multiple networks or subnets. In this case you define multiple routes for a
particular interface, usually a LAN port. This is a method of supporting multiple
subnets on a single physical media.
To create a static route, use the command:
awplus(config)# ip route {|
} []
