Bridge Wan

The following scenario shows how to configure the hardware switch to forward traffic from LAN to WAN and vice versa.

Test Forwarded Traffic Through An Isolated Port

Description

In this scenario, switch port eth0p0 behaves as an isolated port and forwards traffic through eth2.

Scenario

Step 1: Set the following configuration in DUT0:

set interfaces ethernet eth2 address 10.0.0.1/24
set interfaces ethernet eth2 traffic nat source rule 1 address masquerade
set interfaces ethernet eth0p0 address 192.168.100.1/24

Step 2: Set the following configuration in DUT1:

set interfaces ethernet eth0 address 192.168.100.2/24
set protocols static route 0.0.0.0/0 next-hop 192.168.100.1

Step 3: Set the following configuration in DUT2:

set interfaces ethernet eth0 address 10.0.0.2/24

Step 4: Ping IP address 10.0.0.2 from DUT1:

admin@DUT1$ ping 10.0.0.2 count 1 size 56 timeout 1

Show output

PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data.
64 bytes from 10.0.0.2: icmp_seq=1 ttl=63 time=1.89 ms

--- 10.0.0.2 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 1.886/1.886/1.886/0.000 ms

Test Forwarded Traffic Through A Hardware Bridged Port

Description

In this scenario, the hardware switch is configured to forward bridged traffic between eth0 and eth0p0 through eth2. Hardware-offload is enabled.

Scenario

Step 1: Set the following configuration in DUT0:

set interfaces ethernet eth2 address 10.0.0.1/24
set interfaces ethernet eth2 traffic nat source rule 1 address masquerade
set interfaces bridge br0 hardware-offload eth0
set interfaces bridge br0 address 192.168.100.1/24
set interfaces ethernet eth0p0 bridge-group bridge br0

Step 2: Set the following configuration in DUT1:

set interfaces ethernet eth0 address 192.168.100.2/24
set protocols static route 0.0.0.0/0 next-hop 192.168.100.1

Step 3: Set the following configuration in DUT2:

set interfaces ethernet eth0 address 10.0.0.2/24

Step 4: Ping IP address 10.0.0.2 from DUT1:

admin@DUT1$ ping 10.0.0.2 count 1 size 56 timeout 1

Show output

PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data.
64 bytes from 10.0.0.2: icmp_seq=1 ttl=63 time=432 ms

--- 10.0.0.2 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 431.631/431.631/431.631/0.000 ms

Test Forwarded Traffic Through A Software Bridged Port

Description

In this scenario, the hardware switch is configured to forward bridged traffic between eth0 and eth0p0 through eth2. Hardware-offload is disabled.

Scenario

Step 1: Set the following configuration in DUT0:

set interfaces ethernet eth2 address 10.0.0.1/24
set interfaces ethernet eth2 traffic nat source rule 1 address masquerade
set interfaces bridge br0 address 192.168.100.1/24
set interfaces ethernet eth0p0 bridge-group bridge br0

Step 2: Set the following configuration in DUT1:

set interfaces ethernet eth0 address 192.168.100.2/24
set protocols static route 0.0.0.0/0 next-hop 192.168.100.1

Step 3: Set the following configuration in DUT2:

set interfaces ethernet eth0 address 10.0.0.2/24

Step 4: Ping IP address 10.0.0.2 from DUT1:

admin@DUT1$ ping 10.0.0.2 count 1 size 56 timeout 1

Show output

PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data.
64 bytes from 10.0.0.2: icmp_seq=1 ttl=63 time=455 ms

--- 10.0.0.2 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 454.843/454.843/454.843/0.000 ms
