mcproxy downstream interface is not able to function on tunnel interface like pppoe mode.

[Ganesh Reddy]

Dear all, Sebastian, 

I have a problem in below case, please review and  correct, if anything missing ?

mcproxy  downstream interface is not able to function on tunnel interface like pppoe mode  

Details: 

1.configure MCProxy with upstream as  eth1 and downstream as wan-ppp0 (Where wan-ppp0 is PPPoE Client interface  running on top of eth0)
2.start Multicast UDP stream from H2.
3.Start a multicast  listener @H1  over the PPPoE-server end point connected interface. 

4) Though i am able to see the IGMP Join, messages receiving at wan-ppp0  interface of mcproxy  IFCONFIG Rx packats,   the multicast stream is not reaching to H1. ( the route also  updated in ip_mr_cache )

5) Wheras, in place of PPPoE tunnel between H1 and Router, if plain interface is used, then the  Mcast route is forming successfully in Router and able to receive stream at H1.

Queries:

   q1) Is there anything extra configuration to be done for this kind of tunnel interfaces ?

   q2)  Were there any latest patches to address this issue.

H1 ===================================  Mcproxy/Router ====================== H2

                                            (downstream)wan-ppp0/eth0                 eth1(upstream)                  

 pppoe-server                         pppoe-client mode              

Stream Listener                                                                                                                         Stream-Sender

my mcproxy.conf looks as below:

 

protocol IGMPv3;

pinstace myProxy: eth1 ==> wan-ppp0;
