Understanding the effects of disabling OSPF
Consider the following before disabling OSPF on a router:
• If you disable OSPF, the device removes all the configuration information for the disabled protocol
from the running configuration. Moreover, when you save the configuration to the startup
configuration file after disabling one of these protocols, all the configuration information for the
disabled protocol is removed from the startup configuration file.
• If you are testing an OSPF configuration and are likely to disable and re-enable the protocol, you
might want to make a backup copy of the startup configuration file containing the protocol’s
configuration information. This way, if you remove the configuration information by saving the
configuration after disabling the protocol, you can restore the configuration by copying the backup
copy of the startup configuration file into the flash memory.
• If the management default route information is available in the Chassis ID (CID) card, the OSPF
default route is overwritten by the management default route when the switch reboots. In order to
prevent this, remove the management default route after the switch reboots. The OSPF default
route is automatically re-instated. Refer to
Using the Chassis ID (CID) Recovery Tool on page
663.
Disabling OSPF
To disable OSPF on the router, use the no router ospf command:
1. In privileged EXEC mode, issue the configure command to enter global configuration mode.
2. Enter the rbridge-id command followed by the RBridge ID to enter RBridge configuration mode.
3. Issue the no router ospf command to disable OSPF on the router.
switch# configure
switch(config)# rbridge-id 101
switch(config-rbridge-id-101)# no router ospf
