After above configuration, an IPsec tunnel between Device A and Device B should be established, and
the traffic between subnet 10.1.1.0/24 and subnet 10.1.2.0/24 should be IPsec protected.
Example for Establishing an IPsec Tunnel in IKE Negotiation
Mode
Network requirements
• As shown in Figure 6 , an IPsec tunnel is established between Device A and Device B to protect data
flows between subnet 10.1.1.0/24 and subnet 10.1.2.0/24.
• The security protocol to be used is ESP, encryption algorithm is DES, and authentication algorithm
is SHA1-HMAC-96.
Configuration procedure
1. Configure Device A
# Define an ACL to identify data flows from subnet 10.1.1.0/24 to subnet 10.1.2.0/24.
