Network requirements
As shown in Figure 90, configure an IPsec tunnel between Router A and Router 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.

Configuration procedure
1. Configure Router A:
# Define an ACL to identify data flows from subnet 10.1.1.0/24 to subnet 10.1.2.0/24.
