Hello,
i have following scheme:
PE1 -------- CE -------- PE2
|
Multicast Receiver
PE1 - MX480
PE2 - MX80
CE - EX4200
VLAN with IGMP snooping configured on CE. VRRP and VRF with NG-MVPN
configured on PE1 and PE2. IGMP enabled on both CE facing interfaces.
Now both PEs sending multicast streams to receiver, despite on that one
VRRP peer is active, second - passive, which causes unpredicted results
on receiver side. Disabling IGMP or interface from any side makes
everything to work perfect.
I think there should be a way to tell IGMP that it should accept
register messages until router is not VRRP master, but I can't find it.
Any thoughts?
