Routers / igmp joins are received bot router does not send any multicast
« on: December 12, 2017, 03:54:09 am »
I do receive a igmp message report for a join on the mx routers  interface but no multicast is sent, this is only succeeding when I configure a static join for that group on that interface. I do not have any filters on Routing-engine or interface.
The group which is joined is known on the router, it is statically joined on another interface

I do see this message in the igmp log, but can't find anything on www.
 task IGMP socket 57 length 36 flags MSG_DONTROUTE(4) from 0.0.0.0 to 224.0.0.1 out interface 396 in interface 0: (1 retries) No route to host

Routers / loopback interface in igmp
« on: November 16, 2017, 01:28:56 am »
 When configuring the loopback interface in IGMP with a static join the interface is not shown in " show igmp interface" and the group is not shown in "show igm groups". How is that possible.

See config and show commands below
