Command Reference
View This command can be used in the following views:
■ OSPF Area view
Description 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.
