Site-To-Site

This scenario shows how to configure and connect two subnets with each other through a VPN tunnel. The initiator requests an additional IP address from the responder to use as the inner IPsec tunnel address.

rtt min/avg/max/mdev = 0.389/0.389/0.389/0.000 ms

Step 4: Ping IP address 80.0.0.2 from DUT0:

admin@DUT0$ ping 80.0.0.2 count 1 size 56 timeout 1
Show output
PING 80.0.0.2 (80.0.0.2) 56(84) bytes of data.
