In addition to that, about configuring route redistribution, please refer to the related content about
“Route Redistribution” of “Protocol-independent Feather Configurations of IP routing Protocol”.
60.3 OSPF Configuration Tast
60.3.1 Starting OSPF
Like other routing protocols, activating OSPF demands creating OSPF routing process, allocation of an IP
address range related to the executing process, allocation of an area ID related to IP address range. Under
the global configuration mode, use the following commands:
Command Purpose
router ospf
process-id
This command activates OSPF routing protocol, and
enters router configuration mode.
network
address mask
area
area-id
This command configures the interface(s) running OSPF
and the area ID of the interface
60.3.2 Configuring the Interface Parameter of OSPF
During the implementation of OSPF, it is permitted to change the OSPF parameters related to interface
according to the requirement. There is no need to change any parameter, but you should guarantee the identity
of certain parameters on all routers on connected network.
Under interface configuration mode, use the following commands to configure interface parameters:
Command Purpose
ip ospf cost
cost Configure the metric of OSPF interface to forward
packets.
ip ospf retransmit-interval
seconds The seconds taken to retransmit LSA between the
neighbors belonging to the same OSPF interface.
ip ospf transmit-delay
seconds Configure the estimated time to transmit LSA on an
OSPF interface (second as the unit).
ip ospf priority
number Configure the priority of router to become the DR router
ip ospf hello-interval
seconds Configure the time interval to send hello packet on OSPF
interface.
ip ospf dead-interval
seconds If the router does not receive “hello” packet from the
neighbor within the time interval defined, it considers the
neighbor router to be turned off.
ip ospf authentication-key
key It is an authentication password of the adjacent router in
an address, which uses simple password authentication
of OSPF.
ip ospf message-digest-key
keyid
md5
key
Demand OSPF to use MD5 authentication.
ip ospf passive
Do not send “hello” message on the interface.
60.3.3 Configuring OSPF Network Type
No matter what the physical media type of the network is, you can configure your network to be broadcasting
network or non-broadcasting, multi-access network. Using this feature, you can flexibly configure the network,
