5.3.3 Configuring an IPSec Proposal
An IPSec proposal defines the security protocol, authentication algorithm, encryption algorithm,
and packet encapsulation mode. Both ends of a tunnel must use the same IPSec proposal
configuration.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
ipsec proposal proposal-name
An IPSec proposal is created and the IPSec proposal view is displayed.
Step 3 (Optional) Run:
transform { ah | esp | ah-esp }
The security protocol is specified.
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 specified.
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 specified.
By default, both ESP and AH use the MD5 authentication algorithm.
You can configure the authentication and encryption algorithms only after selecting a security
protocol using the transform command.
Step 6 (Optional) Run:
esp encryption-algorithm [ 3des | des | aes-128 | aes-192 | aes-256 ]
The encryption algorithm used by ESP is specified.
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 tunnel mode is used.

5.3.4 Configuring an IPSec Policy
After establishing an IPSec tunnel manually, configure an IPSec policy for the tunnel.
