Verifying the configuration
# Initiate a connection from subnet 10.1.1.0/24 to subnet 10.1.2.0/24 to trigger IKE negotiation. After
IPsec SAs are successfully negotiated by IKE, the traffic between the two subnets is IPsec protected.
# Use the display ipsec sa command to display IPsec SAs on Router A and Router B. This example uses
Router A to verify the configuration.
[RouterA] display ipsec sa
