Configuring a manual mode IPsec tunnel for IPv4 packets
Network requirements
As shown in Figure 97, 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.
<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
# Configure a static route to Host B.
[RouterA] ip route-static 10.1.2.0 255.255.255.0 serial 2/1/1
# Create an IPsec transform set named tran1.
[RouterA] ipsec transform-set tran1
# Specify the encapsulation mode as tunnel.
[RouterA-ipsec-transform-set-tran1] encapsulation-mode tunnel
