Router configuration
| Release | Modification | 10.0 | This command was introduced. |
|---|
Using the area-password command on all routers in an area will prevent unauthorized routers from injecting false routing information into the linkstate database.
This password is exchanged as plain text and thus this feature provides only limited security.
This password is inserted in Level 1 (station router level) link state PDUs (LSPs), complete sequence number PDUs (CSNPs), and partial sequence number PDUs (PSNP).
The following example assigns an area authentication password:
router isis area-password angel
| Command | Description |

| domain-password | Configures the IS-IS routing domain authentication password. |
| isis password | Configures the authentication password for an interface. |
