Static Routes
If the SAN Router is responding to an IP packet that originated from,
for example, the SNMP management station on 10.1.4.2, then it needs
to be told to route the response over the management port to the SAN
Router 10.1.3.1. Static routes are used for this purpose. An entry is
made in the static route table telling the SAN Router to route all
traffic destined to 10.1.4.1 (the IP mask is included to define a range
of addresses) to the next hop SAN Router, 10.1.3.1.
The SAN Router supports three types of static route entries: a
standard entry, a default gateway entry, and a permanent route
entry. All of these entries are stored in flash memory and restored
after the system is reset.
The permanent route is intended for management traffic and is listed
separately on the bottom of the
Static Routing Configuration
dialog box
(
Figure 2-19
on page 2-38). A permanent route differs from a
standard static route because it cannot be deleted and remains
present even when the system is reset to the factory defaults. Use this
route for traffic to your primary network management station to
ensure management connectivity even when the system is reset to the
factory defaults.
A default route is a static route with a mask of 0.0.0.0 (meaning all
traffic). The default route is used if no other route matches the
destination address. The default route is also called the “default
gateway.”
Traffic that matches more than one route entry will be routed using
the entry with the longest (most specific) subnet mask. Therefore, the
default route will only be used to route traffic that is not otherwise
defined in the static route table.
To manually enter routes, follow these instructions:
1. Select
Configuration
>
Static Routing
to display the
Static Routing
Configuration
dialog box.
