Select encryption algorithm
Set the encryption algorithm to the
default value
By default, the 56-bit DES algorithm in CBC mode is adopted.
III. Selecting authentication method
IKE authentication has two algorithms: pre-shared-key and PKI (rsa-signature).
Perform the following configuration in IKE proposal view.

default value
IV. Selecting Authentication-algorithming Algorithm
This configuration is used to specify the authentication algorithm used by an IKE
proposal.
Perform the following configuration in IKE proposal view.
Table 8-5 Select authentication algorithm
Select authentication algorithm
Set authentication algorithm to the
default value
By default SHA-1 authentication algorithm is adopted.
V. Selecting Diffie-Hellman Group ID
