encapsulation dot1q X1
interface <ifname1.10> l2transport
encapsulation dot1q Y1
interface <ifname2.10> l2transport
encapsulation dot1q Y1
interface <ifname3.10> l2transport
encapsulation dot1q Y1
l2vpn
ethernet ring g8032 <ring-name>
port0 interface <main port ifname1>
port1 interface none #? This router is connected to an interconnection node
open-ring #? Mandatory when a router is part of an open-ring
instance <1-2>
inclusion-list vlan-ids X1-Y1
aps-channel
Port0 interface <ifname1.1>
Port1 none #? This router is connected to an interconnection node
