Configuring an IKE keychain
Perform this task when you configure the IKE to use the pre-shared key for authentication.
Follow these guidelines when you configure an IKE keychain:
Two peers must be configured with the same pre-shared key to pass pre-shared key authentication.
You can specify the local address configured in IPsec policy or IPsec policy template view (using the local-address command) for the IKE keychain to be applied. If no local address is configured, specify the IP address of the interface to which the IPsec policy is applied.
You can specify a priority number for the IKE keychain. To determine the priority of an IKE keychain:
The device examines the existence of the match local address command. An IKE keychain with the match local address command configured has a higher priority.
If a tie exists, the device compares the priority numbers. An IKE keychain with a smaller priority number has a higher priority.
If a tie still exists, the device prefers an IKE keychain configured earlier.
To configure the IKE keychain:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Create an IKE keychain and enter its view. | ike keychain keychain-name | By default, no IKE keychain exists. |
3. Configure a pre-shared key. | In Release 1111:pre-shared-key { address { ipv4-address [ mask | mask-length ] | ipv6 ipv6-address [ prefix-length ] } | hostname host-name } key { cipher cipher-key | simple simple-key } In Release 1121 and later:
| By default, no pre-shared key is configured. For security purposes, all pre-shared keys, including those configured in plain text, are saved in cipher text to the configuration file. |
4. (Optional.) Specify a local interface or IP address to which the IKE keychain can be applied. | match local address { interface-type interface-number | { ipv4-address | ipv6 ipv6-address } } | By default, an IKE keychain can be applied to any local interface or IP address. |
5. (Optional.) Specify a priority for the IKE keychain. | priority number | The default priority is 100. |
