Chapter 6 Configuring OSPFv2
Configuring Basic OSPFv2
DETAILED STEPS
Command Purpose
Step 1
config t
Example:
switch# config t
switch(config)#
Enters configuration mode.
Step 2
interface interface-type slot/port
Example:
switch(config)# interface ethernet 1/2
switch(config-if)#
Enters interface configuration mode.
Step 3
ip ospf authentication [message-digest]
Example:
switch(config-if)# ip ospf
authentication
Enables interface authentication mode for OSPFv2 for
either cleartext or message-digest type. Overrides
area-based authentication for this interface. All
neighbors must share this authentication type.
Step 4
ip ospf authentication key-chain
key-name
Example:
switch(config-if)# ip ospf
authentication key-chain Test1
(Optional) Configures interface authentication to use
key chains for OSPFv2. See the Cisco Nexus 7000
Series NX-OS Security Configuration Guide, Release
4.x for details on key chains.
Step 5
ip ospf authentication-key [0 | 3 | 7]
key
Example:
switch(config-if)# ip ospf
authentication-key 0 mypass
(Optional) Configures simple password authentication
for this interface. Use this command if the
authentication is not set to key-chain or
message-digest.
The options are as follows:
• 0—configures the password in clear text.
• 3—configures the pass key as 3DES encrypted.
7—configures the key as Cisco type 7 encrypted.
Step 6
ip ospf message-digest-key key-id md5 [0
| 3 | 7]
key
Example:
switch(config-if)# ip ospf
message-digest-key 21 md5 0 mypass
(Optional) Configures message digest authentication
for this interface. Use this command if the
authentication is set to message-digest.The key-id
range is from 1 to 255. The MD5 options are as
follows:
• 0—configures the password in clear text.
• 3—configures the pass key as 3DES encrypted.
• 7—configures the key as Cisco type 7 encrypted.
Step 7
show ip ospf instance-tag interface
interface-type slot/port
Example:
switch(config-if)# show router ospf 201
interface ethernet 1/2
(Optional) Displays OSPF information.
Step 8
copy running-config startup-config
Example:
switch(config)# copy running-config
startup-config
(Optional) Saves this configuration change.
