Configuring An Ikev2 Policy - HP MSR Series Configuration Manual

Step
14. (Optional.) Set the
IKEv2 NAT keepalive
interval.
15. (Optional.) Enable the
configuration exchange
feature.
16. (Optional.) Enable AAA
authorization.

Configuring an IKEv2 policy

During the IKE_SA_INIT exchange, each end tries to find a matching IKEv2 policy, using the IP
address of the local security gateway as the matching criterion.
•
If IKEv2 policies are configured, IKEv2 searches for an IKEv2 policy that uses the IP address of
the local security gateway. If no IKEv2 policy uses the IP address or the policy is using an
incomplete proposal, the IKE_SA_INIT exchange fails.
•
If no IKEv2 policy is configured, IKEv2 uses the system default IKEv2 policy default.
The device matches IKEv2 policies in the descending order of their priorities. To determine the
priority of an IKEv2 policy:
1. First, the device examines the existence of the match local address command. An IKEv2
policy with the match local address command configured has a higher priority.
2. If a tie exists, the device compares the priority numbers. An IKEv2 policy with a smaller priority
number has a higher priority.
3. If a tie still exists, the device prefers an IKEv2 policy configured earlier.
To configure an IKEv2 policy:
Step
1. Enter system view.
2. Create an IKEv2 policy and
enter IKEv2 policy view.
3. Specify the local interface or
address used for IKEv2
policy matching.
4. Specify a VPN instance for
IKEv2 policy matching.
5. Specify an IKEv2 proposal
for the IKEv2 policy.
6. Specify a priority for the
IKEv2 policy.

Remarks
By default, the global IKEv2 NAT
keepalive setting is used.
By default, all configuration
exchange options are disabled.
By default, AAA authorization is
disabled for IKEv2.
Remarks
N/A
By default, an IKEv2 policy named
default exists.
By default, no local interface or
address is used for IKEv2 policy
matching, and the policy matches
any local interface or address.
By default, no VPN instance is
specified for IKEv2 policy
matching. The IKEv2 policy
matches all local addresses in the
public network.
By default, no IKEv2 proposal is
specified for an IKEv2 policy.
By default, the priority of an IKEv2
policy is 100.
