Configuring an IPsec Site-to-Site VPN with Manual Keying
Next, you configure the VPN traffic selector, which determines which
traffic is selected by the policy. For example, the selector might specify
all IP traffic between 192.168.2.0/24 (a local network) and 192.168.3.0/24
(a remote network). For a policy with the Apply action, the selected traffic
is the traffic that is sent and received (and secured) on the IPsec SA.
Refer to Figure 4-165 for help in configuring the traffic selector.
