This reports whether the east link of this virtual ring is the designated RPL owner responsible for keeping that link blocked under normal ring conditions. A ring should have exactly one RPL owner overall, on one link, west or east, of one node, so an admin who finds this reading owner(2) here needs to confirm the west-side RPL owner object on this same virtual ring, both here and on other nodes, reads none, otherwise the ring has a duplicate-owner provisioning mismatch. For example, a ring topology where the physical RPL owner site sits to this node's east would show owner(2) here and none on the west-side RPL object for the same virtual ring.
