Check Sit

This scenario shows how to configure a SIT tunnel with an IPv6 address and check ICMP connectivity.

Test ICMP Connectivity In SIT Tunnels

Description

A tunnel interface is configured in each node and the ‘Ping’ command is used to check network connectivity (ICMP protocol).

Scenario

Step 1: Set the following configuration in DUT0:

set interfaces ethernet eth0 address 192.168.100.10/24
set interfaces tunnel tun0 address '10::10/24'
set interfaces tunnel tun0 encapsulation sit
set interfaces tunnel tun0 local-address 192.168.100.10
set interfaces tunnel tun0 remote-ip 192.168.100.20
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT1:

set interfaces ethernet eth0 address 192.168.100.20/24
set interfaces tunnel tun0 address '10::20/24'
set interfaces tunnel tun0 encapsulation sit
set interfaces tunnel tun0 local-address 192.168.100.20
set interfaces tunnel tun0 remote-ip 192.168.100.10
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 3: Ping IP address 10::20 from DUT0:

admin@DUT0$ ping 10::20 count 1 size 56 timeout 1
