# Disabling the IS-IS Protocol

The protocol shutdown command disables the IS-IS protocol but does not remove any IS-IS configuration. In addition, even though the router does not participate in IS-IS routing after you issue the protocol shutdown command, you can continue to configure IS-IS.

Issuing the protocol shutdown command:

- Clears the LSP database
- Removes all IS-IS routes in the routing information database (RIB)
- Deletes all adjacencies with the IS-IS instance

  | Note: Rebooting the router does not affect the state of the IS-IS protocol.

protocol shutdown

- Use to disable the IS-IS protocol without removing the IS-IS configuration.
- Example
  `
  host1(config-router)#protocol shutdown
  `
- Use the no version to reenable the IS-IS protocol.
- See protocol shutdown
