I wasn't sure if it would also bridge other protocols, since these are not related to DECnet as such. One can tunnel most anything over GRE, even raw Ethernet frames, regardless of the higher-level protocols. Hence the 'G' for "Generic". Yes. But you need some ingress and egress that makes use of it. Or else we could just as well argue that UDP can tunnel anything. ...which it can. ;) On a Cisco, assigning a DECnet cost to an interface (and a GRE endpoint is a pseudo-interface on a Cisco) forms that ingress/egress.
