Sparse mode autorp listener

I am doing a really basic configuration in Narbik's Multicast unsing autorp
listener. I entered the solution verbatim and can't seem to get it to work.

I have entered the following commands on all routers

ip multicast-routing
ip pim autorp listener

ip pim sparse-mode <- on every interface

Then on one route I enter

ip pim send-rp-announce Loopback0 scope 5
ip pim send-rp-discovery Loopback0 scope 5 interval 5

Problem is that I don't see the PIM Group-to-RP Mappings at ANY router other
than the one this is configured on.

I do a debug and see
*Mar 1 01:15:25.547: Auto-RP(0): Build RP-Discovery packet
*Mar 1 01:15:25.547: Auto-RP: Build mapping (224.0.0.0/4, RP:1.1.1.3),
PIMv2 v1,
*Mar 1 01:15:25.551: Auto-RP(0): Send RP-discovery packet of length 48 on
Serial1/0.32 (1 RP entries)
*Mar 1 01:15:25.555: Auto-RP(0): Send RP-discovery packet of length 48 on
Serial1/0.35 (1 RP entries)
*Mar 1 01:15:25.555: Auto-RP(0): Send RP-discovery packet of length 48 on
Loopback0(*) (1 RP entries)

So it is sending, but I see nothing at the routers directly attached when
debugging. GNS error???
