Command Mode

Command Usage
◆
The RPL neighbor node, when configured, is a ring node adjacent to the RPL
that is responsible for blocking its end of the RPL under normal conditions (i.e.,
the ring is established and no requests are present in the ring) in addition to the
block at the other end by the RPL Owner Node. The RPL neighbor node may
participate in blocking or unblocking its end of the RPL, but is not responsible
for activating the reversion behavior.
◆
Only one RPL owner can be configured on a ring. If the switch is set as the RPL
owner for an ERPS domain, the west ring port is set as one end of the RPL. If the
switch is set as the RPL neighbor for an ERPS domain, the east ring port is set as
the other end of the RPL.
◆
The east and west connections to the ring must be specified for all ring nodes
using the
ring-port command. When this switch is configured as the RPL
neighbor, the east ring port is set as being connected to the RPL.
◆
Note that is not mandatory to declare a RPL neighbor.
