Site-To-Site
This scenario shows how to configure and connect two subnets
with each other through a VPN tunnel and automatically configure
the negotiated remote prefixes as routes. DUT0 acts as a
responder and DUT1 as a initiator.

Note
The tunnel with the lowest metric configured in the route-priority parameter should be the one used to route the traffic.
Step 11: Run command vpn ipsec clear sa at DUT1 and expect this output:

Step 14: Initiate a tcp connection from DUT1 to DUT0 and try to send some messages between both endpoints
admin@DUT0$ monitor test connection server 8080 tcp admin@DUT1$ monitor test connection client 10.1.0.1 8080 tcp local-address 10.3.0.1
Step 15: Run command vpn ipsec show sa at DUT0 and check if output matches the following regular expressions:

Note
Now we will shutdown the tunnel with the lowest metric from DUT1 and check if the traffic is routed through the backup tunnel.
