Example 4: EPSR with Nested VLANs

Example 4: EPSR with Nested VLANs

In this example:

client switches A and C are in the same end-user VLAN (vlan20)

client switches B and D are in the same end-user VLAN (vlan200)

traffic for vlan20 and vlan200 is nested inside vlan50 for transmission around the core

vlan50 is the data VLAN for the EPSR domain

vlan100 is the control VLAN for the EPSR domain
