This object holds the actual sequence of ring-number and bridge-number pairs that make up the source route to a remote Token Ring segment, or an empty string when the destination is on the local ring. An admin configures this to manually define the path frames should take across a series of Token Ring bridges when automatic route discovery is not being used. For example, a populated value might encode a path through ring 100, then bridge 2, then ring 200, describing a two-hop route to a distant ring.
