Hello Vladimir
I have also the same problem with my asr 9001 i release 5.1.1
My configuration is same as yours.
To understand the problem for troubleshoot (if someone have an idea for us), I've done some additionnal investigations and here are the results:
Session pppoe up (show subs ses xxx):
These 2 sessions are playing mcast stream 239.58.203.0:
show igmp group
Show mrib route
If pppoe1469 zap to another channel (239.52.15.24), source 239.58.203.0 disappear on "Outgoing Interface List" (normal state), But the next stream chosen (239.52.15.24) doesn't work, and we have following output:
If pppeo1469 zap again to previous stream (2039.58.203.0), I have following output:
At this state:
* pppoe1459 is still steaming 239.58.203.0 (as I didn't touch it until...)
* and pppoe1469 do not stream 239.58.203.0
If I compare both sessions on outgoing list, i can see difference (O/O/CPU0 which is ASR9001-Line Card on pppoe1459 only).
So my understanding is that once the stream is "removed" from a LC for a specific access, the system cannot play it anymore for this access. The only way is to disconnect/reconnect again pppoe session.
I've found a excellent Cisco live presentation from Xander Thuijs about multicast on asr9k, but i didn't found an issue.
So any idea is welcome...

Hello,
I was downgrade to version 4.3.2 a problem such disappeared, but there was
another at connection of several thousand clients periodically vanishes
the stream but when switching starts working for other group. I drew a conclusion
that it is mistakes in software as the configuration was identical at 5.1.1 and 4.3.2, and symptoms different.
Do you known what version of software on presentation.
some days work for 4.3.2 some hundred clients normally.

Hello Vladimir
No release has been specified on the presentation, but you can have a look at http://d2zmdbbm9feqrf.cloudfront.net/2013/usa/pdf/BRKSPG-2904.pdf. The presentation is really interesting.
FYI, I have opened a case at Cisco support and a caveat is actually running. I hope having soon a SMU for 5.1.1.
12-02-2018 07:09 PM
Hello
Just to inform that this problem (multicast over PPPoE) is solved with 5.1.3 and ONLY 5.1.3
Later release starting from 5.3.x to 6.3.x still have small bug:
* multicast over PPPoE, work and stop (stream freeze after 10/20min)
* need to zap all the time
5.1.3 dont have this problem.

Optimal multicast performance is achieved when multicast is not forwarded across subscriber interfaces. The downstream access node should support IGMP snooping and forward multicast where required. A separate VLAN should be used for multicast.
If access switches don't support UGMP snooping, you can still achieve some optimisation by configuring passive multicast in the dynamic template:
dynamic-template type ppp <name>
multicast ipv4 passive
igmp explicit-tracking enable
igmp query-interval <seconds>
igmp query-max-response-time <seconds>
Hope this helps,
