Globally configuring IS-IS on a device

Configuring authentication

By default, the device does not authenticate packets sent to or received from ESs or other ISs. You
can configure the following types of passwords for IS-IS globally.
TABLE 130
Password type
Domain
Area
Interface
If you configure a password, the device checks for the password in IS-IS packets received by the
device and includes the password in packets sent by the device. For example, the device checks all
Level-2 LSPDUs received by the device for the domain password you configure, and includes the
password in all Level-2 PDUs sent by the device.
Configuring a domain password
To configure an IS-IS domain password, enter a command such as the following.
BigIron RX(config-isis-router)# domain-password domain-1
This command configures the device to use the password "domain-1" to authenticate Level-2
LSPDUs.
Syntax: [no] domain-password <string>
The <string> parameter specifies the password. You can enter an alphanumeric string up to 80
characters long. The password can contain blank spaces. If you use a blank space in the password,
you must use quotation marks (" ") around the entire password; for example, domain-password
"domain 1".
Configuring an area password
To configure an IS-IS area password, enter a command such as the following.
BigIron RX(config-isis-router)# area-password area-51
This command configures the device to use the password "area-51" to authenticate Level-1
LSPDUs.
Syntax: [no] area-password <string>
The <string> parameter specifies the password. You can enter an alphanumeric string up to 80
characters long. The password can contain blank spaces. If you use a blank space in the password,
you must use quotation marks (" ") around the entire password; for example, area-password "area
51".

Changing the IS-IS Level globally

By default, a BigIron RX can operate as both a Level-1 and IS-IS Level-2 router. To globally change
the level supported from Level-1 and Level-2 to Level-1 only, enter the following command.
BigIron RX(config-isis-router)# is-type level-1
