Multiple Default Routes

Default routes are used to route data that is being addressed to a remote destination and that does not have a specific route defined. Default routes are based on the availability of the next hop router and the type of service (TOS). If no specific TOS is requested, the first available default route with TOS of *NORMAL is used.

If a default route is not defined, only the networks explicitly defined by any non-default routes appear as though TCP/IP can reach them, and datagrams bound for any undefined networks are not sent.

Note: A default route cannot have a subnetwork; therefore, you must leave the subnet mask at the default value of *NONE.

Consult “Multiple Routes” on page 61 for further information about multiple default routes and the type of service (TOS) parameter.
