IPsec configuration examples
Configuring a manual mode IPsec tunnel for IPv4 packets
Network requirements
As shown in
, establish an IPsec tunnel between Switch A and Switch B to protect data flows
between the switches. Configure the tunnel as follows:
•
Specify the encapsulation mode as tunnel, the security protocol as ESP, the encryption algorithm as
AES-CBC-192, and the authentication algorithm as HMAC-SHA1.
•
Manually set up IPsec SAs.

Configuration procedure
1.
Configure Switch A:
# Configure an IP address for VLAN-interface 1.
<SwitchA> system-view
[SwitchA] interface vlan-interface 1
[SwitchA-Vlan-interface1] ip address 2.2.2.1 255.255.255.0
[SwitchA-Vlan-interface1] quit
# Define an ACL to identify data flows from Switch A to Switch B.
[SwitchA] acl number 3101
[SwitchA-acl-adv-3101] rule 0 permit ip source 2.2.2.1 0 destination 2.2.3.1 0
[SwitchA-acl-adv-3101] quit
# Create an IPsec transform set named
tran1
.
