3. Verify the configuration:
After the configuration, IKE negotiation is triggered to set up SAs when there is traffic between
subnet 10.1.1.0/24 and subnet 10.1.2.0/24. Physical interfaces Ethernet 1/1 and Ethernet 1/2
will use the shared source interface to negotiate IPsec SAs dynamically.
# Execute the display ipsec sa command. The output shows that the local address and peer
address of the IPsec tunnel are respectively the IP addresses of the two shared interfaces.
