Verifying the configuration
After the configuration, an IPsec tunnel between SecPath A and SecPath 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.
IKE-based IPsec tunnel for IPv4 packets configuration example
Network requirements
As shown in Figure 127 , configure an IPsec tunnel between SecPath A and SecPath B to protect data flows
between subnet 10.1.1.0/24 and subnet 10.1.2.0/24. Configure the tunnel to use the security protocol
ESP, the encryption algorithm DES, and the authentication algorithm SHA1-HMAC-96.
Configuring SecPath A
# Define an ACL to identify data flows from subnet 10.1.1.0/24 to subnet 10.1.2.0/24.
