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.
Test Site-To-Site With Basic Route Installation

In this scenario, both devices install routes
for the VPN traffic in the main table.

Step 10: Run command show system route ip at DUT0 and check if output contains the following tokens:

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:
Show output
Deleting IPSec SAs... 100.0% Closed tunnels: 1
Step 12: Run command vpn ipsec initiate peer PEER at DUT1 and expect this output:

Step 13: Ping IP address 10.1.0.1 from DUT1:
admin@DUT1$ ping 10.1.0.1 local-address 10.3.0.1 count 1 size 56 timeout 1Show output
PING 10.1.0.1 (10.1.0.1) from 10.3.0.1 : 56(84) bytes of data. 64 bytes from 10.1.0.1: icmp_seq=1 ttl=64 time=0.331 ms --- 10.1.0.1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.331/0.331/0.331/0.000 ms
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.
