(config vpn ipsec tunnel ipsec_example ike phase1_proposal 0)>
ii. Set the Diffie-Hellman group type:
(config vpn ipsec tunnel ipsec_example ike phase1_proposal 0)>
dh_group value
(config vpn ipsec tunnel ipsec_example ike phase1_proposal 0)>
The default is modp2048.
v. (Optional) Add additional phase 1 proposals:
i. Moveback one level in the schema:
(config vpn ipsec tunnel ipsec_example ike phase1_proposal 0)>
..
(config vpn ipsec tunnel ipsec_example ike phase1_proposal)>
ii. Add an additional proposal:
(config vpn ipsec tunnel ipsec_example ike phase1_proposal)>
add end
(config vpn ipsec tunnel ipsec_example ike phase1_proposal 1)>
Repeat the above steps to set the type of encryption, hash, and Diffie-Hellman
group for the additional proposal.
iii. Repeat to add more phase 1proposals.
j. Configure the typesof encryption, hash, and Diffie-Hellman group to use during phase 2:
i. Moveback 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)>
