Check Vti To Dum

This scenario shows how to configure and route traffic via one VTI (Virtual Tunnel Interface) device.

Test VTI To Dummy

Description

In the left side, a VTI device is configured. In the right side, a global security association is created to match with a dummy IP address.

Scenario

Step 1: Set the following configuration in DUT0:

set vpn ipsec site-to-site peer PEER connection-type on-demand
set vpn ipsec site-to-site peer PEER vti local-prefix 10.0.0.1/32
set vpn ipsec site-to-site peer PEER vti remote-prefix 20.0.0.1/32
set vpn ipsec site-to-site peer PEER local-address 192.168.100.10
set vpn ipsec site-to-site peer PEER remote-address 192.168.100.20
set interfaces ethernet eth0 address 192.168.100.10/24
set interfaces vti vti0 address 10.0.0.1/32
set interfaces vti vti0 ipsec PEER
set protocols static route 0.0.0.0/0 interface vti0
set vpn ipsec auth-profile AUTH-SA local auth pre-shared-secret test
set vpn ipsec esp-group CHILD-SA proposal 1 encryption aes256gcm128
set vpn ipsec esp-group CHILD-SA proposal 1 pfs dh-group19
set vpn ipsec ike-group IKE-SA key-exchange ikev2
set vpn ipsec ike-group IKE-SA proposal 1 dh-group 19
set vpn ipsec ike-group IKE-SA proposal 1 encryption aes256gcm128
set vpn ipsec ike-group IKE-SA proposal 1 hash sha256
set vpn ipsec site-to-site peer PEER default-esp-group CHILD-SA
set vpn ipsec site-to-site peer PEER auth-profile AUTH-SA
set vpn ipsec site-to-site peer PEER ike-group IKE-SA

Step 2: Set the following configuration in DUT1:

set vpn ipsec site-to-site peer PEER connection-type initiate
set vpn ipsec site-to-site peer PEER tunnel 1 local prefix 20.0.0.1/32
set vpn ipsec site-to-site peer PEER tunnel 1 remote prefix 10.0.0.1/32
set vpn ipsec site-to-site peer PEER tunnel 1 esp-group CHILD-SA
set vpn ipsec site-to-site peer PEER local-address 192.168.100.20
set vpn ipsec site-to-site peer PEER remote-address 192.168.100.10
set interfaces ethernet eth0 address 192.168.100.20/24
set interfaces dummy dum0 address 20.0.0.1/32
set protocols static route 0.0.0.0/0 interface dum0
set vpn ipsec auth-profile AUTH-SA local auth pre-shared-secret test
set vpn ipsec esp-group CHILD-SA proposal 1 encryption aes256gcm128
set vpn ipsec esp-group CHILD-SA proposal 1 pfs dh-group19
set vpn ipsec ike-group IKE-SA key-exchange ikev2
set vpn ipsec ike-group IKE-SA proposal 1 dh-group 19
set vpn ipsec ike-group IKE-SA proposal 1 encryption aes256gcm128
set vpn ipsec ike-group IKE-SA proposal 1 hash sha256
set vpn ipsec site-to-site peer PEER default-esp-group CHILD-SA
set vpn ipsec site-to-site peer PEER auth-profile AUTH-SA
set vpn ipsec site-to-site peer PEER ike-group IKE-SA

Step 3: Run command vpn ipsec show sa at DUT0 and check if output contains the following tokens:

ESTABLISHED

Step 4: Ping IP address 20.0.0.1 from DUT0:

admin@DUT0$ ping 20.0.0.1 count 1 size 56 timeout 1

Step 5: Run command vpn ipsec show sa at DUT0 and check if output matches the following regular expressions:

,\s+[^0] packets
