igmp join-group/static-group are not showing up in ip mroute output

Hello gents

The setup is  RTR-A ***** RTR-B********RTR-C

router B is the RP

I am running PIM BIDIR on this network.

RTR-A is Cisco 4300, RTR-C is Cisco 2911.

I want clients on LAN segments of RTR-A and RTR-C be able to mutually communicate

to a group 232.112.112.112.

Clients are not able to send igmp reports, hence I am using ip igmp static-group 232.112.112.112

(ip igmp joinn-group is not working either)

 

On RTR-C I correctly see the output

 

(*,232.112.112.112), 1d02h/-, RP 172.23.223.129, flags: BC
Bidir-Upstream: GigabitEthernet0/0.28581150, RPF nbr: 172.23.223.65
Incoming interface list:
GigabitEthernet0/0/0.80, Accepting/Sparse
GigabitEthernet0/0.28581150, Accepting/Sparse
Outgoing interface list:
GigabitEthernet0/0/0.80, Forward/Sparse, 00:25:22/00:01:37
Gi0/0.28581150, Bidir-Upstream/Sparse, 01:02:22/stopped

and as you can see, there is C flag, indicating, that I have configured ip igmp static-group 232.112.112.112

 on interface Gig0/0/0.80 hence the stream will flow down to LAN.

and I can see 

RTR-C#sh ip pim vrf voice interface gigabitEthernet 0/0/0.80 df 
* implies this system is the DF
Interface                RP               DF Winner        Metric     Uptime
GigabitEthernet0/0/0.80  172.23.223.129   *10.186.223.2     0          1d02h

 On RTR-A on other hand I can not see the latter  

RTR-A#sh ip pim vrf voice interface gigabitEthernet 0/0/2.80 df
* implies this system is the DF
Interface                RP               DF Winner        Metric     Uptime

and I can not see the LAN segment to be in incomming nor outgoing interface lists for the group

  

RTR-A#sh ip mroute vrf voice 232.112.112.112
(*,232.112.112.112), 1d02h/-, RP 172.23.223.129, flags: B
  Bidir-Upstream: GigabitEthernet0/0/0.36151150, RPF nbr: 172.23.223.129
  Incoming interface list:
    GigabitEthernet0/0/0.36151150, Accepting/Sparse

even if I have ip igmp static-group 232.112.112.112 configured on Gig0/0/0.80

  

RTR-A#sh ip igmp vrf voice membership 232.112.112.112
Channel/Group Reporter Uptime Exp. Flags Interface
*,232.112.112.112 0.0.0.0 00:15:32 stop 2SA Gi0/0/2.80
RTR-A#

 How to force the RTR-A to be the DF and get the correct output to my sh ip mroute table.

 

This is the initial state I had it in. And then I lost OIL completelty on RTR-A and there was no config change. 

(*,232.112.112.112), 1d02h/-, RP 172.23.223.129, flags: B
  Bidir-Upstream: GigabitEthernet0/0/0.36151150, RPF nbr: 172.23.223.129
  Incoming interface list:
    GigabitEthernet0/0/0.36151150, Accepting/Sparse
  Outgoing interface list:
    Gi0/0/0.36151150, Bidir-Upstream/Sparse, 00:00:07/stopped

 funny stuff is, that the traffic is allegedly flowing both ways, but from the outputs it should not at all.

 

Any hints please?

Thank you very much

Leo
