Verifying the configuration
After the previous configurations, an IPsec tunnel between Router A and Router B is established, and the
traffic between subnet 10.1.1.0/24 and subnet 10.1.2.0/24 is IPsec protected.
Use the display ipsec sa command to display IPsec SAs on Router A and Router B. Take Router A as an
example:
