you're right. R1's and R3's token rings don't see each other in this
configuration. You have to either establish another peering between
R1 & R3, or set on R2 dlsw local-peer....border.

promiscious mode isn't an issue here. You set a peer in promiscious
mode if you don't wanna establish two-way peering, and let this router
accept any dlsw connections.
