Internet Protocol (IP) Routing
•
By issuing the CLI superuser route command. This lets you define a static route during the
Model 5390 session, thereby avoiding the need to change the configuration file and reboot.
However, the route only remains defined for the duration of the session. If the Model 5390
server is rebooted, the route disappears.
Entering Routes in the Model 5390 Configuration File
The sections that follow describe how to enter routes in annex...end and subnet...end blocks in the
gateway section of the Model 5390 configuration file. Usually, the configuration file path name is
/usr/spool/erpcd/bfs/config.annex on the load host; you can modify this file using an editor such
as vi.
You can define routes anywhere in the gateway section of the configuration file, but routes not in
an annex...end or subnet...end block are discarded and not cached if they apply to interfaces that
are immediately operational at boot time. Typically, the Ethernet interface is operational
immediately, but SLIP and PPP interfaces may be slower to come up.
You may also want to set a default route and/or static routes in the configuration file of one or more
hosts on your network. On a Berkeley-style UNIX host, define these routes in the /etc/gateways file.
Purpose of a Default Route
The Model 5390 server uses its default route when it cannot find a route in the routing table for a
particular destination. Initially, no default route is defined. If the Model 5390 server receives a default
route in a RIP update, it learns and uses it. Or, you can configure a default route using the method
described in this section. Once configured, this route is not replaced by any learned routes.
Default Route Entry Format
To define a default route for the Model 5390 server, create an entry in the following format in the
gateway section of the Model 5390 configuration file:
%gateway
annex
IP_addr
route add
[–h]
default
gateway_address [metric]
end
IP_addr is the address of the Model 5390 server that will use the default route; gateway_address is
the IP address the Model 5390 server will use as the default gateway; and metric is the cost of using
this default gateway.
