Configuring IP Routing 14-9
1
The default value of the network mask will be configured automatically, to reflect the
appropriate address class, after an IP address is specified. (
Network Mask
is determined
by
Source IP Address
, and
NetMask
is determined by
Sec. IP Addr
.)
If the interface is
configured as unnumbered (and, therefore, no
Source IP Address
is configured), the
default value of
Network Mask
will be taken from the numbered interface that is
assigned.
If an IP address (
Source IP Address/Sec. IP Addr
) is specified/
changed, the network mask will automatically change to
default values appropriate for the new address. For this
reason, configure the IP address first, then the mask.
2
The default value of the broadcast address will be configured automatically after an IP
address or a network mask is specified. The value will be the dotted decimal notation
result of "ANDing" the binary versions of the IP address and the network mask, then
filling in the remaining bits with
1
s. (
Broadcast Address
is associated with
Source IP
Address
and
Network Mask
, while
Bcast Addr
is associated with
Sec. IP Addr
and
Ne t Ma sk
.)
If the (
Source IP Address/Sec. IP Addr
) or
Network Mask/Netmask
is specified/changed, the associated broadcast address
will automatically change to default values appropriate
for the new address. For this reason, configure the IP
address first, then the mask, then the broadcast address.
