Verifying the configuration
After the configuration, traffic between Host A (10.1.1.2) and Host B (10.2.2.2) should be able to trigger
IKE negotiation. After IPsec SAs are established, traffic between Host A and Host B should be transferred
through the IPsec tunnel, and Firewall A should synchronize its IKE SA and IPsec SAs to Firewall B.
# Display the active IPsec SAs on Firewall A.
<FirewallA> display ipsec sa active
