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 remote-ip 192.168.100.20
set interfaces tunnel tun0 encapsulation sit
set interfaces tunnel tun0 local-address 192.168.100.10

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 remote-ip 192.168.100.10
set interfaces tunnel tun0 encapsulation sit
set interfaces tunnel tun0 local-address 192.168.100.20

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

admin@DUT0$ ping 10::20 count 1 size 56 timeout 1
Show output
PING 10::20(10::20) 56 data bytes
64 bytes from 10::20: icmp_seq=1 ttl=64 time=4.09 ms

--- 10::20 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 4.085/4.085/4.085/0.000 ms
