Hi,
My server(10.194.35.16) has to communicate to my client(10.194.90.15) over multicat address 239.255.0.127 udp port 8192.I have enable ip multicat on all the interface on the path as below,
""ip multicast- routing"
on int
"ip pim spare-dense-mode"
There is no Firewall in the way but communication is failing by giving "socket error" on client.
Is any way I can trace or troubleshoot this issue?
Regards,

could you send the topology diagram. If multicast runs on two paths then may be the RPF could fail. But first need to check the design. Please post it.

YES,
there is active and passive switches on the way, can I check the RFP?

Hello Mohammed,
use sh ip rpf source-address
to check if the traffic arrives from the RPF neighbor
Hope to help

6509#sh ip rpf 10.194.35.16
RPF information for ? (10.194.35.16)
RPF interface: Vlan124
RPF neighbor: ? (0.0.0.0) - directly connected
RPF route/mask: 10.194.35.0/26
RPF type: unicast (connected)
RPF recursion count: 0

Hello Mohammed,
this is from the switch that is connected to the source.
RPF type: unicast (connected)
You should check using the same command on the other devices those near the receiver.
In this way you can detect if there is an RPF issue caused by the topology.
Hope to help
