Example 4: EPSR with Nested VLANs

3.Configure client switch E (connected to the master node)

create vlan=vlan20 vid=20

add vlan=20 port=20 frame=tagged

enable ip

add ip interface=vlan20 ip=192.168.20.10

4.Configure client switch F (connected to transit node B)

create vlan=vlan200 vid=200

add vlan=200 port=10 frame=tagged

enable ip

add ip interface=vlan200 ip=192.168.200.1

5.Configure client switch G (connected to transit node C)

create vlan=vlan20 vid=20

add vlan=20 port=20 frame=tagged

enable ip

add ip int=vlan20 ip=192.168.20.1

6.Configure client switch H (connected to transit node D)

create vlan=vlan200 vid=200
