	Yes, you can make a folded ring.  It will state in
"show stp topology" that the ring is in wrap, but that is normal
operation until the ring is healed.

 Topology Map for Interface SRP0/0
  Topology pkt. sent every 5 sec. (next pkt. after 0 sec.)
  Last received topology pkt. 00:00:04
  Last topology change was 1w2d ago.
  Nodes on the ring: 2
  Hops (outer ring)      MAC       IP Address      Wrapped SRR   Name
      0             0008.7db1.c000   1.1.1.1        Yes     -   router.A 
      1             000c.8567.ac00   1.1.1.2        Yes     -   router.B

	Nope, just plug the end, or get another circuit to finish the ring. :)
The SRP ring will consider the second side as down, and will be in a failure
mode, not ideal, but it would work.
