Configuring IP Routing 14-9
1The 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 dete rmined b y Sec. IP Addr .)
If the interface is
configured as unnumbered (and, therefore, no Source IP Address is configured), the
defau lt 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 sp ecified/
changed, the network mask will automatically change to
default values appropriate for the new address. For this
reason, co nfigure the I P address firs t, then the mask.
2The 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 "AND ing" the b inary versions of the I P address and the networ k mask, th en
filli ng in the r emainin g bits wi th 1s. (Broadcast Address is associated with Source IP
Address and Network Mask, while Bca s t Ad d r is associated with Sec. IP Addr and
NetM ask.) 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.
