Configuring the Node of an Open Ring: Example

This example shows you how to configure the node part of an open ring. The following figure illustrates an
open ring scenario.
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
aps-channel
Port0 interface <ifname1.1>
Port1 none #? This router is connected to an interconnection node
bridge-domain bd-aps#? APS-channel has its own bridge domain
<ifname1.1> #? There is only one APS-channel at the interconnection node
bridge-domain bd-traffic #? Data traffic has its own bridge domain
<ifname1.10>
<ifname2.10>
<ifname3.10>
