Syntax Description
Defaults The default configuration routes the local network through the sc0 interface with m etric 0 as soon as sc0
is configured.
Command Types Switch command.
Command Modes Privileged.
Usage Guidelines You can configure up to three default gateways. The primary is the highest priority. If you do not
designate a primary gateway, priority is based on the order of input. If you enter two primary definitions,
the second definition becomes the primary and the first definition becomes the secondary default IP
gateway.
You can only specify the primary keyword for a default route.
When you enter the destination value or gateway value, enter it in dot notation, for example, a.b.c.d.
When you specify the netmask value, this indicates the number of bits allocated to subnetting in the
hostid section of the given Class A, B, or C address. For example, if you enter an IP address for the sc0
interface as 172.22.20.7, the hostid bits for this Class B address is 16. Any number of bits in the hostid
bits can be allocated to the netmask field. If you do not enter the netmask value, the number of bits is
assumed to be the natural netmask.
When you enter the netmask, enter it as the number of bits or dot format, for example, destination/24
or destination/255.255.255.0. If you enter the netmask in dot forma t, you m ust h ave conti guo us 1s .
