Enabling OSPFv2 Authentication
To enable or change various OSPF authentication parameters, use the following commands.
• Set a clear text authentication scheme on the interface.
CONFIG-INTERFACE mode
ip ospf authentication-key key
Configure a key that is a text string no longer than eight characters.
All neighboring routers must share password to exchange OSPF information.
• Set the authentication change wait time in seconds between 0 and 300 for the interface.
CONFIG-INTERFACE mode
ip ospf auth-change-wait-time seconds
This setting is the amount of time OSPF has available to change its interface authentication type.
During the auth-change-wait-time, OSPF sends out packets with both the new and old
authentication schemes.
This transmission stops when the period ends.
The default is 0 seconds.
Enabling OSPFv2 Graceful Restart
Graceful restart is enabled for the global OSPF process.
For more information, refer to Graceful Restart.
The Dell Networking implementation of OSPFv2 graceful restart enables you to specify:
•grace period — the length of time the graceful restart process can last before OSPF terminates it.
•helper-reject neighbors — the router ID of each restart router that does not receive assistance from
the configured router.
•mode — the situation or situations that trigger a graceful restart.
