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.

Show output
Codes: K - kernel route, C - connected, L - local, S - static,
       R - RIP, O - OSPF, I - IS-IS, B - BGP, E - EIGRP, N - NHRP,
       T - Table, v - VNC, V - VNC-Direct, A - Babel, F - PBR,

L>* 90.0.0.1/32 is directly connected, eth1, weight 1, 00:00:09

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

10.3.0.0/24 via 90.0.0.3 dev eth1 proto static metric 100
10.3.0.0/24 via 80.0.0.2 dev eth0 proto static metric 10
Show output

80.0.0.0/24 dev eth0 proto kernel scope link src 80.0.0.1
90.0.0.0/24 dev eth1 proto kernel scope link src 90.0.0.1

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:

Show output
Initiating IPSec SAs... 0.0%
Initiated tunnels: 1

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 1
Show 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=0.288 ms

--- 10.1.0.1 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.288/0.288/0.288/0.000 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:

[1-9]\d? packets

    remote 10.3.0.0/24

Note

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

Step 16: Run command vpn ipsec clear sa at DUT1 and expect this output:

Show output
Deleting IPSec SAs... 100.0%
Closed tunnels: 1

Step 17: Run command vpn ipsec clear sa at DUT2 and expect this output:

Show output
Deleting IPSec SAs... 100.0%
Closed tunnels: 1

Step 18: Run command vpn ipsec initiate peer PEER at DUT2 and expect this output:

Show output
Initiating IPSec SAs... 0.0%
Initiated tunnels: 1

Step 19: Ping IP address 10.1.0.1 from DUT2:

admin@DUT2$ ping 10.1.0.1 local-address 10.3.0.1 count 1 size 56 timeout 1
Show output
PING 10.1.0.1 (10.1.0.1) from 10.3.0.1 : 56(84) bytes of data.

rtt min/avg/max/mdev = 0.277/0.277/0.277/0.000 ms

Step 20: Initiate a tcp connection from DUT2 to DUT0 and try to send some messages between both endpoints

admin@DUT0$ monitor test connection server 8080 tcp
admin@DUT2$ monitor test connection client 10.1.0.1 8080 tcp local-address 10.3.0.1

Step 21: Run command vpn ipsec show sa at DUT0 and check if output matches the following regular expressions:

[1-9]\d? packets
Show output

Step 22: Run command show system route ip at DUT0 and check if output contains the following tokens:

10.3.0.0/24 via 90.0.0.3 dev eth1 proto static metric 100
Show output
10.1.0.0/24 dev dum0 proto kernel scope link src 10.1.0.1
