[Xorp-users] Regarding pimsm4 and igmp protocols configuration.

[Ganesh Reddy K]

Hi,

I have installed XORP on a PC.   Below is the configuration.

>From H1 i am sending Multicast UDP traffic (DIP is 239.11.11.12)
On H2  i subscribed (IGMP JOIN) to the same Group  using a utility and
waiting for the stream to receive..

In summary i have enabled IGMP protocol configuration on both the
interfaces of PC. pimsm configuration is disabled for the same.

After starting UDP stream on H1 and Subcription from  H2, i am unable to
see the stream on H2 side. I verified in the XORP show configuration that,
JOIN to the group  239.11.11.12 is registered properly. But Dataflow has
not been established.

The multicast route is verified in /proc/net/ip_mr_cache also. The route is
not  completely formed. OutIface is given as -1 only.


Is the configuration correct ?  What should be the expected behavior ?
