442BConfiguring 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 acl-number
[ aggregation | per-host ]
By default, an IPsec policy
references no ACL.
5. Assign IPsec transform sets to
the IPsec policy.
transform-set
transform-set-name&<1-6>
By default, an IPsec policy
references no IPsec transform set.
6. Specify an IKE peer for the
IPsec policy.
ike-peer peer-name N/A
7. Enable and configure the
perfect forward secrecy
feature for the IPsec policy.
pfs { dh-group1 | dh-group2 |
dh-group5 | dh-group14 }
Optional.
By default, the PFS feature is not
used for negotiation.
For more information about PFS,
see "Configuring IKE."
The dh-group1 keyword is not
available for FIPS mode.
8. Set the SA lifetime.
sa duration { time-based seconds |
traffic-based kilobytes }
Optional.
By default, the global SA lifetime is
used.
