[j-nsp] proxy-arp on EVPN irb

Hi

Maybe somebody knows the answer to this one:

We migrated some customers to an EVPN domain away from a legacy node that used proxy-arp on its L3 interface.

The downstream clients have some funky routing and they are relying on proxy-arp to resolve an offnet address (don't ask me why for our sanities sake)!

We have a implemented EVPN bridge domain with the following config on MX PE nodes running 21.1 code.

instance-type virtual-switch;
protocols {
    evpn {
        encapsulation mpls;
        default-gateway do-not-advertise;
        extended-vlan-list [ 250  ];
    }
}
bridge-domains {
    250 {
        domain-type bridge;
        vlan-id 250;
        interface ae68.250;
        routing-interface irb.25068;
    }
}

interfaces irb.25068 {
  proxy-arp;
  family inet {
      address 172.23.248.1/22;
  }
  mac 00:aa:dd:00:00:68;
}

This irb is in a L3VPN instance.

Now the documentation states that proxy-arp and arp-suppression is on by default yet these clients cant reach the offnet host with or without the "proxy-arp" command on the irb.

Any ideas?

thanks
