Applying the Keychain

Applying the Keychain

Context

The keychain only takes effect after it is applied to an application.

This section uses RIP as an example to describe how to apply the keychain to applications. Different applications may use different commands to apply the Keychain. Table 17-4 lists the commands used by different applications.
Table 17-4 Protocols that support the keychain authentication

RIP

MSDP

OSPF

ospf authentication-mode

IS-IS

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. On an Ethernet interface, run undo portswitch

    The interface is switched to Layer 3 mode.

    By default, an Ethernet interface works in Layer 2 mode.

    The mode switching function takes effect when the interface only has attribute configurations (for example, shutdown and description configurations). Alternatively, if configuration information supported by both Layer 2 and Layer 3 interfaces exists (for example, mode lacp and lacp system-id configurations), no configuration that is not supported after the working mode of the interface is switched can exist. If unsupported configurations exist on the interface, delete the configurations first and then run the undo portswitch command.

    NOTE:

    If many Ethernet interfaces need to be switched to Layer 3 mode, run the undo portswitch batch interface-type { interface-number1 [ to interface-number2 ] } &<1-10> command in the system view to switch these interfaces to Layer 3 mode in batches.

  4. Run rip authentication-mode md5 nonstandard { keychain keychain-name | { plain plain-text | [ cipher ] password-key } key-id }

    The keychain used by RIP is configured.

    NOTE:

    When configuring an authentication password, select the ciphertext mode because the password is saved in the configuration file as a simple text if you select the plaintext mode, which has a high risk.

  5. Run commit

    The configuration is committed.
