Check Ipip

This scenario shows how to configure an IP-in-IP tunnel and check ICMP connectivity.

Test ICMP Connectivity In IP-in-IP 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 10.0.0.10/24
set interfaces tunnel tun0 remote-ip 192.168.100.20
set interfaces tunnel tun0 encapsulation ipip
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 10.0.0.20/24
set interfaces tunnel tun0 remote-ip 192.168.100.10
set interfaces tunnel tun0 encapsulation ipip
set interfaces tunnel tun0 local-address 192.168.100.20

Step 3: Ping IP address 10.0.0.20 from DUT0:

admin@DUT0$ ping 10.0.0.20 count 1 size 56 timeout 1
