If this is used in conjunction with one of the commands, the tables are cleared prior to running the command. -p When used with the ADD command, makes a route persistent across boots of the system. By default, routes are not preserved when the system is restarted. When used with the PRINT command, displays the list of registered persistent routes. Ignored for all other commands, which always affect the appropriate persistent routes. This option is not supported Windows'95. command One of these: PRINT Prints a route ADD Adds a route DELETE Deletes a route CHANGE Modifies an existing route destination Specifies the host.

GATEWAY Specifies gateway. interface the interface number for the specified route. METRIC Specifies the metric, ie. cost for the destination. All symbolic names used for destination are looked up in the network database file NETWORKS. The symbolic names for gateway are looked up in the host name database file HOSTS. If the command is PRINT or DELETE. Destination or gateway can be a wildcard, (wildcard is specified as a star '*'), or the gateway argument may be omitted. If Dest contains a * or ?, it is treated as a shell pattern, and only matching destination routes are printed. The '*' matches any string, and '?' matches any one char. Examples: 157.*.1, 157.*, 127.*, *224*. Diagnostic Notes: Invalid MASK generates an error, that is when (DEST & MASK) != DEST.

Only prints those matching 157* >route DELETE 157.0.0.0 >route PRINT One way to use this would be as follows: You can't ping the server that you are connecting to, but you know the ip address to be 127.16.16.10 >route PRINT Interface List 0x1 ...........................
