a complicated problem
I have a problem with Multicast recieving in VPLS attached to IES interface, the traffic is unstable, i also notice when zapping between channels and going back to the same channel (fast re-join 2 seconds after the last leave) the udp stream stops while states on R1 below that its active! , although no packets are sent out the Interface.
I cant find anything that fix the unstability issue , i think there is a problem in backplane forwarding between IES interface and SAPs inside the VPLS
The topology is as follows:
Reciever 1 --- --- R2 7750SR------------
R1 7750SR===== =====Source
Reciever 2 --- --- R3 7750SR -------------
Some facts about the topology
1- Recievers are working in IGMPv3
2-recievers are configured with no specific sources
3- R1,R2,R3 are confiugred with PIM SSM
4-IES interface is configured as IGMP querier
5- VPLS service is configured with IGMP-snooping send-queries
6-PIM neighbor relation with R2 R3 have no problem
7-static ssm translation is configured on all routers (no RP)
What i did tried to modify with no luck
1-Igmp query intervals
2-Last member query interval
3- tried looking into the vpls fdp igmp and it states that the channel 232.0.1.150 is fwded to the user
4-show ip pim group 232.0.1.150 details is showing that traffic is recieved via R1 PIM interface and sent to IES_Video interface
5- show service id 23212310 igmp-snooping port-db sap 6/1/1:100.* detail shows that MC group 232.0.1.150 is active to SAP.
