Check Vti To Global Ipsec

This scenario shows how to configure and route traffic via one VTI (Virtual Tunnel Interface) device. The other end-point does not use VTI devices, but a global IPSec policy.

Test VTI To Global IPSec

Description

A tunnel is configured between DUT0 and DUT1. On the one hand, in DUT0, a vti interface is configured to encapsulate traffic. On the other hand, in DUT1, an IPSec policy with global selectors is configured.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 60.0.0.10/24
set interfaces ethernet eth1 address 192.168.10.1/24
set interfaces vti vti0 ipsec PEER
set interfaces vti vti0 local-address 60.0.0.10

set vpn ipsec site-to-site peer PEER vti remote prefix 192.168.20.0/24

Step 2: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 60.0.0.20/24
set interfaces ethernet eth1 address 192.168.20.1/24
set protocols static route 0.0.0.0/0 interface eth0
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

set vpn ipsec site-to-site peer PEER tunnel 1 remote prefix 192.168.10.0/24

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

ESTABLISHED

Step 4: Run command vpn ipsec show sa at DUT1 and check if output contains the following tokens:

ESTABLISHED

Step 5: Ping IP address 192.168.10.1 from DUT1:

admin@DUT1$ ping 192.168.10.1 local-address 192.168.20.1 count 1 size 56 timeout 1

Step 6: Ping IP address 192.168.20.1 from DUT0:

admin@DUT0$ ping 192.168.20.1 local-address 192.168.10.1 count 1 size 56 timeout 1

Step 7: Run command vpn ipsec show sa at DUT0 and check if output matches the following regular expressions:

,\s+[^0] packets
