j. Configure the types of encryption, hash, and Diffie-Hellman group to use during phase 2:
i. Move back two levels in the schema:
(config vpn ipsec tunnel ipsec_example ike phase1_proposal 0)> ..
..
(config vpn ipsec tunnel ipsec_example ike)>
ii. Add a phase 2 proposal:
(config vpn ipsec tunnel ipsec_example ike)> add ike phase2_
proposal end
(config vpn ipsec tunnel ipsec_example ike phase2_proposal 0)>
iii. Set the type of encryption to use during phase 2:
(config vpn ipsec tunnel ipsec_example ike phase2_proposal 0)>
cipher value
(config vpn ipsec tunnel ipsec_example ike phase2_proposal 0)>
where value is one of 3des, aes128, aes192, aes256, or null. The default is 3des.
iv. Set the type of hash to use during phase 2 to verify communication integrity:
(config vpn ipsec tunnel ipsec_example ike phase2_proposal 0)>
hash value
(config vpn ipsec tunnel ipsec_example ike phase2_proposal 0)>
where value is one of md5, sha1, sha256, sha384, or sha512. The default is sha1.
v. Set the type of Diffie-Hellman group to use for key exchange during phase 2:
i. Use the ? to determine available Diffie-Hellman group types:
(config vpn ipsec tunnel ipsec_example ike phase2_proposal 0)>
dh_group ?
curve25519
curve448
ecp192
ecp224
...
(config vpn ipsec tunnel ipsec_example ike phase2_proposal 0)>
ii. Set the Diffie-Hellman group type:
(config vpn ipsec tunnel ipsec_example ike phase2_proposal 0)>
dh_group value
(config vpn ipsec tunnel ipsec_example ike phase2_proposal 0)>
The default is modp2048.
vi. (Optional) Add additional phase 2 proposals:
