204 CHAPTER 6: USING ROUTING PROTOCOL COMMANDS
ip_mask
Enter the IP address mask or IP address wildcard shielded text (similar to
the complement of the IP address mask).
Description
Using the network command, you can configure the interface running OSPF
protocol to which the interface belongs.
Using the undo network command, you can cancel the interface running OSPF. By
default, the interface does not belong to any area.
With the two parameters,
ip_address
and
ip_mask
, one or more interfaces can
be configured as an area. To run the OSPF protocol on one interface, the master IP
address of this interface must be in the range of the network segment specified by
this command. If the slave IP address of the interface is in the range of the
network segment specified by this command, this interface will not run OSPF
protocol.
Related command: ospf.
Example
To configure the interfaces whose master IP addresses are in the segment range of
10.110.36.0 to run the OSPF protocol, and to specify the number of the OSPF area
where these interfaces are located as 6, enter the following:
<SW5500>system-view
System View: return to User View with Ctrl+Z.
[SW5500]router id 1.1.1.1
[SW5500]ospf
[SW5500-ospf-1]area 6
[SW7700-ospf-1-area-0.0.0.6]network 10.110.36.0.0 0.0.0.255
