Huawei AR1200 Series Configuration Guide

By default, the ESP protocol defined in RFC 2406 is used.
Step 4 (Optional) Run:
ah authentication-algorithm { md5 | sha1 | sha2-256 | sha2-384 | sha2-512 }
The authentication algorithm used by AH is configured.
By default, AH uses the MD5 authentication algorithm.
Step 5 (Optional) Run:
esp authentication-algorithm [ md5 | sha1 | sha2-256 | sha2-384 | sha2-512 ]
The authentication algorithm used by ESP is configured.
By default, ESP uses the MD5 authentication algorithm.
Step 6 (Optional) Run:
esp encryption-algorithm { 3des | des | aes-128 | aes-192 | aes-256 }
The encryption algorithm used by ESP is configured.
By default, ESP uses the DES encryption algorithm.
Step 7 (Optional) Run:
encapsulation-mode { transport | tunnel }
The packet encapsulation mode is configured.
By default, the security protocol uses the tunnel mode to encapsulate IP packets.

5.4.6 Configuring an IPSec Policy
After configuring an IKE peer, apply it to an IPSec policy. Then the two ends can start IKE
negotiation.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
ipsec policy policy-name seq-number isakmp [ template template-name ]
An IPSec policy is created.
Step 3 Run:
proposal proposal-name
An IPSec proposal is applied to the IPSec policy.
An IPSec policy that uses IKE negotiation can reference a maximum of six IPSec proposals.
During IKE negotiation, the two ends of the IPSec tunnel use the IPSec proposals with the same
parameter settings first.
Step 4 Run:
