3. Verify the configuration:
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.

Configuring an IKE-based IPsec tunnel for IPv4 packets

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.
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.
<RouterA> system-view
[RouterA] acl number 3101
[RouterA-acl-adv-3101] rule permit ip source 10.1.1.0 0.0.0.255 destination 10.1.2.0
0.0.0.255
[RouterA-acl-adv-3101] quit
