I can make MVR work on 1 switch but not two.

Can someone have a look please?

Thanks

RESULT:

!r3 ----> OK

r3#sh ip mroute count
IP Multicast Statistics
3 routes using 1588 bytes of memory
2 groups, 0.50 average sources per group
Forwarding Counts: Pkt Count/Pkts per second/Avg Pkt Size/Kilobits per second
Other counts: Total/RPF failed/Other drops(OIF-null, rate-limit etc)

Group: 226.1.1.1, Source count: 1, Packets forwarded: 0, Packets received:
1353
  Source: 10.34.1.4/32, Forwarding: 0/-1/0/0, Other: 1353/0/1353

!r5 -----> NOT OK

r5#sh ip mroute count
IP Multicast Statistics
2 routes using 1300 bytes of memory
2 groups, 0.00 average sources per group
Forwarding Counts: Pkt Count/Pkts per second/Avg Pkt Size/Kilobits per second

TROUBLESHOOTING

1) !r5 is connected to the correct port

r5#sh cdp nei
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
                  S - Switch, H - Host, I - IGMP, r - Repeater

Device ID Local Intrfce Holdtme Capability Platform Port ID
sw2 Fas 0/1 147 S I WS-C3550-2Fas 0/5

2) Switch 2 is trunking properly

sw2#sh int trunk

Port Mode Encapsulation Status Native vlan
Fa0/13 auto 802.1q trunking 1

Port Vlans allowed on trunk
Fa0/13 1-4094

Port Vlans allowed and active in management domain
Fa0/13 1,4-5,342

Port Vlans in spanning tree forwarding state and not pruned
Fa0/13 1,4-5,342

3) MVR is configured poperly

sw2#sh mvr
MVR Running: TRUE
MVR multicast VLAN: 4
MVR Max Multicast Groups: 256
MVR Current multicast groups: 1
MVR Global query response time: 5 (tenths of sec)
MVR Mode: dynamic

sw2#sh mvr interface
Port Type Status Immediate Leave
---- ---- ------- ---------------
Fa0/5 RECEIVER ACTIVE/UP DISABLED
