Radoslave,
can you try with ip pim sparse-dense mode on loopback0 interface of your R2
router?

Subject: AutoRP on a single subnet issue
Hi Group,
The following issue drives me bananas. Part of my multicast task is to
configure AutoRP and am currently trying to achieve this on a single subnet
over VLAN 258.
Three routers there - R2, R5, and Switch2.
I'm trying to configure R2 as both a candidate RP and mapping agent:
ip pim send-rp-announce Loopback0 scope 20 interval 10 ip pim
send-rp-discovery Loopback0 scope 20
the interface connected to vlan 258:
interface FastEthernet0/0
ip address 141.1.0.2 255.255.255.0
ip pim sparse-dense-mode
duplex auto
speed auto
interface Loopback0
ip address 150.1.2.2 255.255.255.0
ip pim sparse-mode
Now, going to Swtich2, which is Cisco 3750, 12.2(25) SEB4:
configuration:
ip mroute 150.1.2.2 255.255.255.255 141.1.0.2 ip route 150.1.2.2
255.255.255.255 141.1.0.2
interface Loopback0
ip address 150.1.8.8 255.255.255.0
ip pim sparse-dense-mode
interface Vlan258
ip address 141.1.0.8 255.255.255.0
ip pim sparse-dense-mode
Rack1SW2#sh ip pim rp map
PIM Group-to-RP Mappings
Rack1SW2#sh ip mroute

Outgoing interface list:

As seen above, 150.1.2.2 (R2 loopback) is sending discovery messages, they
are received on Vlan258 in this switch, but no successfull RP mappings are
installed.
Rack1SW2#sh ip route
S 150.1.5.5/32 [1/0] via 141.1.0.5
S 150.1.2.2/32 [1/0] via 141.1.0.2
C 150.1.8.0/24 is directly connected, Loopback0
B 205.90.31.0/24 [200/0] via 141.1.0.2, 00:16:34
O*IA 0.0.0.0/0 [110/2] via 141.1.0.5, 00:16:48, Vlan258
[110/2] via 141.1.0.2, 00:16:48, Vlan258
debug ip pim autorp doesn't give me any output!
Any ideas?
