QFX3500 and... multicast forward (VRRP related)

[Xavier Beaudouin]

Hello there,

I have a strange clue with an QFX3500-48S4Q, and with "simple" VRRP setup.

On port xe-0/0/6.0 I have a infrastructure (cisco switches) with a VLAN 3016 who want to be VRRP with an MX204 on et-0/1/0.0.

Current config of the switch :

interfaces {
    xe-0/0/6 {
        description "Core: to sw01 (10G 1550nm)";
        ether-options {
            auto-negotiation;
            flow-control;
        }
        unit 0 {
            family ethernet-switching {
                interface-mode trunk;
                vlan {
                    members [ HCT-MGMT AP-Datacenter NAT ];
                }
                storm-control default;
            }
        }
    }
    et-0/1/0 {
        description "Core: mx204 {et-0/0/0}";
        ether-options {
            auto-negotiation;
            flow-control;
        }
        unit 0 {
            family ethernet-switching {
                interface-mode trunk;
                vlan {
                    members [ AP-Datacenter NAT ];
                }
                storm-control default;
            }
        }
    }
}
vlans {
    AP-Datacenter {
        description AP-Datacenter;
        vlan-id 3016;
    }
    NAT {
        description "NATed Customers";
        vlan-id 3085;
    }
}

Pretty "simple" configuration.

When I monitor traffic interface et-0/1/0.0 match vrrp I see the VRRP comming MX204 and on xe-0/0/6.0 I see also VRRP comming TO the QFX...
Is there any reason why VRRP on the VLAN is not forwarded between et-0/1/0.0 and xe-0/0/6.0 ?

Did I missed something ?

Kind regards,
Xavier
