This object identifies the RPL Next Neighbor port of the ring. When a port is configured as a RPL Next Neighbor port, that node becomes RPL Next Neighbor for that ring. [Reference : Section VIII.4 of ITU-T G.8032 Y.1344 (03/2010)] Value '2' indicates that this ring port is not a RPL Next Neighbor port. Both the RPL owner and RPL Next Neighbor node cannot be enabled at the same Ethernet Ring Node. Administrator has to ensure that, only nodes in a ring which are adjacent to the RPL owner or RPL Neighbor node are configured as RPL Next Neighbor Nodess.
