After the configuration, an IPsec tunnel between Router A and Router 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.

Network requirements
As shown in
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.
