Configuring an IKE profile

An IKE profile is intended to provide a set of parameters for IKE negotiation. To configure an IKE
profile, you can do the following:
1. Configure peer IDs. When an end needs to select an IKE profile, it matches the received peer
ID against the peer IDs of its local IKE profiles. If a match is found, it uses the IKE profile with
the peer ID for IKE negotiation.
2. Configure the IKE keychain or PKI domain for the IKE proposals to use:
To use digital signature authentication, configure a PKI domain.
To use pre-shared key authentication, configure an IKE keychain.
3. Specify the negotiation mode (main or aggressive) that the device uses as the initiator. When
the device acts as the responder, it uses the IKE negotiation mode of the initiator.
4. Specifies the IKE proposals that the device can use as the initiator. An IKE proposal specified
earlier has a higher priority. When the device acts as the responder, it uses the IKE proposals
configured in system view to match the IKE proposals received from the initiator. If no match is
found, the negotiation fails.
5. Configure the local ID, the ID that the device uses to identify itself to the peer during IKE
negotiation:
For digital signature authentication, the device can use an ID of any type. If the local ID is an
IP address that is different from the IP address in the local certificate, the device uses the
FQDN (the device name configured by using the sysname command) instead.
For pre-shared key authentication, the device can use an ID of any type other than the DN.
6. Configure the IKE DPD function to detect dead IKE peers. You can also configure this function
in system view. The IKE DPD settings configured in the IKE profile takes precedence over
those configured in system view.
7. Specify a local interface or IP address for the IKE profile so the profile can be applied only to the
specified interface or IP address. For this task, specify the local address configured in IPsec
policy view (using the local-address command). If no local address is configured, specify the
IP address of the interface that references the IPsec policy.
8. Specify a priority number for the IKE profile. To determine the priority of an IKE profile:
a. The device examines the existence of the match local address command. An IKE profile
with the match local address command configured has a higher priority.
b. If a tie exists, the device compares the priority numbers. An IKE profile with a smaller priority
number has a higher priority.
c. If a tie still exists, the device prefers an IKE profile configured earlier.
To configure an IKE profile:
Step
1. Enter system view.
2. Create an IKE profile and
enter its view.
3. Configure a peer ID.
