Example 2: A Double Ring

Configure EPSR:

create epsr=domain2 mode=transit controlvlan=vlan40

add epsr=domain2 datavlan=vlan50

enable epsr=domain2

5.Configure the transit node (switch E) that belongs to both domains

Two separate EPSR domains are configured on this switch.

Configure the control VLAN for domain 1:

create vlan=vlan1000 vid=1000

add vlan=1000 port=1-2 frame=tagged

Configure the control VLAN for domain 2:

create vlan=vlan40 vid=40

add vlan=40 port=4-5 frame=tagged

Configure the data VLAN for domain 1:

create vlan=vlan2 vid=2

add vlan=2 port=1-2 frame=tagged

Configure the data VLAN for domain 2:

create vlan=vlan50 vid=50

add vlan=50 port=4-5 frame=tagged

Remove the ring ports from the default VLAN:

delete vlan=1 port=1-2,4-5

Configure EPSR for domain 1. This switch is a transit node:

create epsr=domain1 mode=transit controlvlan=vlan1000

add epsr=domain1 datavlan=vlan2

enable epsr=domain1

Configure EPSR for domain 2. This switch is a transit node:

create epsr=domain2 mode=transit controlvlan=vlan40

add epsr=domain2 datavlan=vlan50

enable epsr=domain2
