NOTE:
You cannot change the creation mode of an IPsec policy from manual to through IKE, or vice versa. To
create an IPsec policy that uses IKE, delete the manual IPsec policy, and then use IKE to confi
g
ure an IPsec
policy.
Configuring an IPsec policy that uses IKE
To configure an IPsec policy that uses IKE, use one of the following methods:
• Directly configure it by configuring the parameters in IPsec policy view.
• Configure it by referencing an existing IPsec policy template with the parameters to be negotiated
configured. A device referencing an IPsec policy that is configured in this way cannot initiate SA
negotiation but can respond to a negotiation request. The parameters not defined in the template
will be determined by the initiator. This approach applies to scenarios where the remote end's
information, such as the IP address, is unknown.
Before you configure an IPsec policy that uses IKE, complete the following tasks:
• Configure the ACLs and the IPsec transform sets for the IPsec policy.
• Configure the IKE peer. For more information about IKE peer configuration, see "Configuring IKE."
The parameters for the local and remote ends must match.
1. Directly configure an IPsec policy that uses IKE:
Ste
p
Command
Remar
k
1. Enter system view.
system-view N/A
2. Create an IPsec policy that
uses IKE and enter its view.
ipsec policy policy-name
seq-number isakmp
By default, no IPsec policy exists.
3. Configure an IPsec connection
name.
connection-name name
Optional.
By default, no IPsec connection
name is configured.
4. Assign an ACL to the IPsec
policy.
security acl [ ipv6 ] acl-number
[ aggregation ]
By default, an IPsec policy does not
reference any ACL.
5. Assign IPsec transform sets to
the IPsec policy.
transform-set
transform-set-name&<1-6>
By default, an IPsec policy does not
reference any IPsec transform set.
With SAs to be established through
IKE negotiation, an IPsec policy
can reference up to six IPsec
transform sets. During negotiation,
IKE searches for a fully matched
IPsec transform set at the two ends
of the expected IPsec tunnel. If no
match is found, no SA can be set
up and the packets expecting to be
protected will be dropped.
6. Specify an IKE peer for the
IPsec policy.
ike-peer peer-name
An IPsec policy cannot reference
any IKE peer that is already
referenced by an IPsec profile, and
vice versa.
