MD5 configuration example

To replicate the above configuration example using the key ID 2 and key value qwsdf89, perform the following steps:

Step Action

1Configure MD5 authentication on R1.

5530-24TFD(config)# interface vlan 2

5530-24TFD(config-if)# ip ospf message-digest-key 2 md5 qwsdf89

5530-24TFD(config-if)# ip ospf primary-md5-key 2

5530-24TFD(config-if)# ip ospf authentication-type message-digest

2Configure MD5 authentication on R2.

5530-24TFD(config)# interface vlan 2

5530-24TFD(config-if)# ip ospf message-digest-key 2 md5 qwsdf89

5530-24TFD(config-if)# ip ospf primary-md5-key 2 5530-24TFD(config-if)# ip ospf authentication-type message-digest

—End—

Configuring OSPF network types

OSPF network types were created to allow OSPF-neighboring between routers over different types of network infrastructures. With this feature, each interface can be configured to support the various network types.

In the example configuration illustrated below, VLAN 2 on Nortel Ethernet Routing Switch 5500 Series R1 is configured for OSPF with the interface type field value set as passive. Because VLAN 2 is set as passive, OSPF hello messages are not sent on this segment, although R1 continues to advertise this interface to the remaining OSPF network.
