Probably the biggest problem in your situation is the lack of RIF between
R3 and R2 (especially given the way you appear to be testing your setup).
On R3 the token ring interface routes IP so any IP packet generated will
not contain a RIF. On R2 the token ring interface is only source route
bridging (not routing) which can only process frames that contain a RIF.
R3 produces a frame without a RIF which cannot be forwarded by R2 so your
attempt to ping as a test will fail.
You might consider generating some non-routed traffic on R3 as a test or
you might try the multiring command on R3 as a way of getting your test
traffic through.
