Chapter 10 Configuring Networking Protocols
Configuring IP Routing
Use the no form of these commands to remove the configured parameter value or return to the
default value.
This is an example of output from the show ip ospf interface privileged EXEC command:
Router# show ip ospf interface
FastEthernet0 is up, line protocol is up
Internet Address 192.168.3.1/24, Area 0
Process ID 1, Router ID 192.168.3.1, Network Type BROADCAST, Cost: 1
Transmit Delay is 1 sec, State DR, Priority 1
Designated Router (ID) 192.168.3.1, Interface address 192.168.3.1
No backup designated router on this network
Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5
Hello due in 00:00:01
Index 2/2, flood queue length 0
Next 0x0(0)/0x0(0)
Last flood scan length is 0, maximum is 0
Last flood scan time is 0 msec, maximum is 0 msec
Neighbor Count is 0, Adjacent neighbor count is 0
Suppress hello for 0 neighbor(s)
POS0 is up, line protocol is up
Internet Address 192.168.2.2/24, Area 0
Process ID 1, Router ID 192.168.3.1, Network Type BROADCAST, Cost: 1
Transmit Delay is 1 sec, State DR, Priority 1
Designated Router (ID) 192.168.3.1, Interface address 192.168.2.2
Backup Designated router (ID) 192.168.2.1, Interface address 192.168.2.1
Step 7
Router(config-if)# ip ospf
hello-interval
seconds
(Optional) Sets the number of seconds between hello
packets sent on an OSPF interface. The value must be the
same for all nodes on a network. The range is
1 to 65535 seconds. The default is 10 seconds.
Step 8
Router(config-if)# ip ospf
dead-interval
seconds
(Optional) Sets the number of seconds after the last device
hello packet was seen before its neighbors declare the
OSPF router to be down. The value must be the same for all
nodes on a network. The range is 1 to 65535 seconds. The
default is 4 times the hello interval.
Step 9
Router(config-if)# ip ospf
authentication-key
key
(Optional) Assigns a password to be used by neighboring
OSPF routers. The password can be any string of
keyboard-entered characters up to 8 bytes in length. All
neighboring routers on the same network must have the
same password to exchange OSPF information.
Step 10
Router(config-if)# ip ospf message
digest-key
keyid
md5
key
(Optional) Enables MDS authentication.
• keyid—Identifier from 1 to 255.
• key—Alphanumeric password of up to 16 bytes.
Step 11
Router(config-if)# ip ospf
database-filter all out
(Optional) Blocks flooding of OSPF LSA packets to the
interface. By default, OSPF floods new LSAs over all
interfaces in the same area, except the interface on which
the LSA arrives.
Step 12
Router(config-if)# end
Returns to privileged EXEC mode.
Step 13
Router# show ip ospf interface
[
interface-name
]
Displays OSPF-related interface information.
Step 14
Router# copy running-config
startup-config
(Optional) Saves your entries in the configuration file.
