Hello,
I have two MX80 router configured for MVPN multicast almost same way -
both receiver only sites. One of the is able to serve multicast to
connected customers, another one - not. Everything is checked - configs
is almost the same, all type routes is in place on both routers, but one
of them simply doesn't serving multicast.
I decided to configure virtual tunnel on that router and it starts
serving multicast, which is wrong for me. According to Juniper, You
should only configure vt interface in sites, where sources are present,
but i explicitly setting them as receiver-site.
Can anybody explain me the situation? The only thing is wrong I've found
on faulty router is that "Wrong incoming interface notifications"
counter is growing, with vt and without it. On other routers everything
is ok.

}
On this router for example everything is fine:

Both are JunOS 12.3R5.7. Any help appreciated.
