set forwarding
120 Chapter 2 Command Descriptions
set forwarding
Device support This command is supported in PortServer TS Family devices only.
Purpose Configures or displays IP routing, or forwarding, options. The
“set forwarding” command can be used to configure a Digi device in the
following ways:
• To function as an IP router using Routing Information Protocol (RIP) to
dynamically maintain routes.
• To perform Proxy ARP services.
• To handle various ICMP-related functions.
Required
permissions
The root user can configure IP routing options. Normal users can display IP
routing options.

set forwarding
Options advertise=time
The interval at which the device server advertises its routes. This option
is used only if "state=active." The range is 10 to 180 seconds. The default
is 30 seconds.
breakoutsubnets={on|off}
Controls how addresses are handled in the routing table when the Digi
device receives RIP routing information.
on
When the Digi device receives an RIP entry that describes a network
that is already subnetted in the routing table, do not add the entry.
off
When the Digi device receives an RIP entry that describes a network
that is already subnetted in the routing table, add the entry to the larger
network in the table, and keep the old, smaller subnet entry.
When leaking routes, and “breakoutsubnets” on, the Digi device sends
each known individual subnet. If “breakoutsubnets” is off, the Digi device
sends out a single entry for the larger network, rather than describing
each individual subnet route.
