Comments
• The N-PE is a 7600 with a OSM or SIP-600 module. Provisioning is the same as the ERS example.
• The U-PE is a generic Metro Ethernet (ME) switch.
• No PACL provisioned by default. BPDU can be tunneled if desired.
• The system MTU needs to set to 1522 to handle the extra 4 bytes of QinQ frames.
