Configuring static routes
The IP route table can receive routes from the following sources:
• Directly-connected networks – When you add an IP interface, the Virtual ADX automatically
creates a route for the network the interface is in.
• Default network route – A statically configured default route that the Virtual ADX uses if other
default routes to the destination are not available. Refer to
“Configuring a default network
route” on page 76.
• Statically configured route – You can add routes directly to the route table. When you add a
route to the IP route table, you are creating a static IP route. This section describes how to add
static routes to the IP route table.
Static route types
You can configure the following types of static IP routes:
• Standard – the static route consists of the destination network address and network mask,
and the IP address of the next-hop gateway. You can configure multiple standard static routes
with the same metric for load sharing or with different metrics to provide a primary route and
backup routes.
• Interface-based – the static route consists of the destination network address and network
mask, and the Virtual ADX interface through which you want the Virtual ADX to send traffic for
the route. Typically, this type of static route is for directly attached destination networks.
• Null – the static route consists of the destination network address and network mask, and the
“null0” parameter. Typically, the null route is configured as a backup route for discarding traffic
if the primary route is unavailable.
Static IP route parameters
When you configure a static IP route, you must specify the following parameters:
• The IP address and network mask for the route’s destination network.
• The route’s path, which can be one of the following:
• The IP address of a next-hop gateway
• An Ethernet port
• A virtual interface (a routing interface used by VLANs for routing Layer 3 protocol traffic
among one another)
• A “null” interface. The Virtual ADX drops traffic forwarded to the null interface.
You also can specify the following optional parameters:
• The route’s metric – The value the Virtual ADX uses when comparing this route to other routes
in the IP route table to the same destination. The metric applies only to routes that the Virtual
ADX has already placed in the IP route table. The default metric for static IP routes is 1.
