12.45 subnet
12.45.1Syntax
subnet
subnet add <name> <i/f> <IP address> <mask>
subnet delete <name>
subnet flush
12.45.2Description
Lists defined subnets; defines a subnet; deletes a subnet definition; or
deletes all subnet definitions.
•
<name> is a label, that can be specified by subnet add and later
used by subnet delete to delete the subnet.
• <i/f> is not used, but is present for historical reasons and must be
specified as either “.” or a valid interface name.
• <IP address> is the IP address of the subnet being defined (only
those bits of <dest> corresponding to bits set in <mask> are
relevant).
• <mask> is the subnet mask of the subnet being defined, specified as
four hexadecimal numbers separated by colons.
A subnet is defined automatically for each interface, with a name
formed by appending
.home to the device name.
The only significant use for the subnet command is to change the masks
for these automatic subnets, if the default masks (see the command
device on page 172) are not correct. (Subnet definitions for other
subnets can also be useful in conjunction with RIP version 1, which
does not communicate subnet masks, but this is not very common.)
Configuration saving saves this information.
