Hi All,

can someone please help me to understand this output. I'm reluctant to believe that all my packets are getting lost in some hops.


xxxx#mstat 192.168.4.178 192.168.4.34 224.1.6.41

Type escape sequence to abort.

Mtrace from 192.168.4.178 to 192.168.4.34 via group 224.1.6.41

From source (elonxm.xx.yy.com) to destination (elonxmd.xx.yy.com)

May be the reason one of the router not belongs to a particular multicast group so its happening. Verify the RP and receivers group.
