To preallocate memory for the routing tables, complete the following tasks:
Using a Default Route for an Unknown Subnet
By default, IP drops packets addressed to an unknown subnet and returns an
ICMP message to the sender. This prevents local traffic from accidentally
following the default route to the Internet.
In cases where remote sites follow a default route to a central site, it is appropriate
to enable this parameter. If the router serves as an Internet gateway (with a default
route to the Internet), the parameter can be disabled.
The default route must be present in the routing table.
