Parameter
ip-address: Address of the network segment where the interface locates.
wildcard: IP address wildcard mask, which is similar to the reversed form of the
mask of IP address. But when configure this parameter, you can type it as mask
of IP address, it could be translated as wildcard mask by VRP system.
Description
Using the network command, you can configure the interface running OSPF. Using
the undo network command, you can cancel the interface running OSPF.
By default, the interface does not belong to any 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 only
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.
After OSPF multi-instance is configured, different OSPF processes are bound with
different VPN instances. The network addresses between different processes can
be the same or included. But for the same VPN instance, the network addresses
between different OSPF processes cannot be the same or included. Otherwise, the
later configured command cannot be valid and the following will be displayed:
Network already set in OSPF process xx, that is, if network 10.1.0.0 0.0.255.255 is
enabled in process 100, network 10.1.0.0 0.0.255.255, network 10.1.1.0
0.0.0.255 or network 10.0.0.0 0.255.255.255 will fail to be enabled in other
OSPF processes.
CAUTION: OSPF configuration can only enable the interfaces that belong to the
same VPN instance.
After OSPF is configured multi-instance, if different VPN instances are bound in
the OSPF process, the network addresses between different processes can be the
same or included. But for the same VPN instance, the network addresses between
different OSPF processes cannot be the same or included.
For the related command, see ospf.
Example
Specify the interfaces whose master IP addresses are in the segment range of
10.110.36.0 to run the OSPF protocol and specify the number of the OSPF area
(where these interfaces are located) as 6.
[3Com-ospf] area 6
[3Com-ospf-1-area-0.0.0.6] network 10.110.36.0.0 0.0.0.255
Enable OSPF process 100 on the router and specify the number of the
area where the interface is located as 2.
[3Com] router id 10.110.1.9
[3Com] ospf 100
[3Com-ospf-100] area 2
[3Com-ospf-100-area-0.0.0.2] network 131.108.20.0 0.0.0.255
Enable OSPF process 200 on the router and specify the number of the
area where the interface is located as 1.
