Hello,

I did at first place, but maybe something wrong went into config, so I thought that PIM shouldn't be UP over that link, so as security measure i set hello interval to 0 to prevent undesired neighbors to appear.

But after Your remark I did it again, with higher priority configured on main link, now everything fine. Thank You very much !

Hello,

Why you use the hello-interval of 0 on PE1 PIM configuration?
While I'm not 100% sure this probably prevents sending hello messages on
segment so potentially  PIM DR election is broken - there is possibility
both PE routers to believe they are DRs for the segment.(PE1 seeing P2'S
hellos elects himself because of highest IP address and PE2 not seeing
neighbor hellos elect himself as one and only pim router on segment)

    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?
