Example 3: EPSR and RSTP

2.Configure the transit node (switch B) that belongs just to the EPSR domain

This transit node (B) is the same as in the previous example.

create vlan=vlan1000 vid=1000

add vlan=1000 port=1-2 frame=tagged create vlan=vlan2 vid=2

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

create epsr=domain1 mode=transit controlvlan=vlan1000 add epsr=domain1 datavlan=vlan2

enable epsr=domain1

3.Configure the switches that belong to the RSTP instance (switches C and D)

Switches C and D have the same configuration in this example.

Configure the STP VLAN:

create vlan=vlan10 vid=10

add vlan=10 port=10-11 frame=tagged

Remove the STP VLAN’s ports from the default VLAN:

delete vlan=1 port=10-11

Configure STP:

create stp=example

add stp=example vlan=vlan10

enable stp=example

set stp=example mode=rapid
