Main mode IKE with pre-shared key authentication
configuration example
Network requirements
As shown in Figure 87, configure an IPsec tunnel that uses IKE negotiation between Device A and Deice
B to secure the communication between subnet 10.1.1.0/24 and subnet 10.1.2.0/24.
Configure Device A and Device B to use the default IKE proposal for the IKE negotiation to set up the
IPsec SAs. Configure the two devices to use the pre-shared key authentication method for the IKE
negotiation phase 1.

Configuration procedure
1. Configure Device A:
# Assign an IP address to each interface. (Details not shown.)
# Configure ACL 3101 to identify traffic from subnet 10.1.1.0/24 to subnet 10.1.2.0/24.
<DeviceA> system-view
[DeviceA] acl number 3101
[DeviceA-acl-adv-3101] rule permit ip source 10.1.1.0 0.0.0.255 destination 10.1.2.0
0.0.0.255
[DeviceA-acl-adv-3101] quit
# Create an IPsec transform set named tran1.
[DeviceA] ipsec transform-set tran1
# Set the packet encapsulation mode to tunnel.
[DeviceA-ipsec-transform-set-tran1] encapsulation-mode tunnel
# Use the ESP protocol for the IPsec transform set.
[DeviceA-ipsec-transform-set-tran1] protocol esp
# Specify the encryption and authentication algorithms.
[DeviceA-ipsec-transform-set-tran1] esp encryption-algorithm aes-cbc-128
[DeviceA-ipsec-transform-set-tran1] esp authentication-algorithm sha1
[DeviceA-ipsec-transform-set-tran1] quit
# Create an IKE keychain named keychain1.
