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
