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
• vlan 1 00 is the control VLAN for the EPSR domain
