[j-nsp] EVPN on QFX5200

[Liam Farr]

Hi,

I'm running VXLAN with ingress-node-replication in prod, can you
explain what you mean by havoc?

e.g.

show vlans

VLAN-NAME {

    interface xe-0/0/2.2;

    no-arp-suppression;

    vxlan {

        vni 561;

        encapsulate-inner-vlan;

        ingress-node-replication;

    }

}

show interfaces xe-0/0/2

flexible-vlan-tagging;

mtu 9216;

encapsulation flexible-ethernet-services;

unit 2 {

    encapsulation vlan-bridge;

    vlan-id 2;

    input-vlan-map pop;

    output-vlan-map push;

}



Cheers

Liam
