[j-nsp] AE loadbalancing with Ethernet CCC over L2VPN

Hello,

I have the following setup:

[CE] == AE(2 links) == [MX80] --- L2VPN --- [MX80] == AE(2 links) == [CE]

The problem is that the MX80s both only send outgoing traffic to the
CE on one link of the AE bundle.

There is no hash-key/enhanced-hash-key configured on the boxes.

The configuration it the same on both sides (with swapped site-ids):

[edit interfaces ae4]
encapsulation ethernet-ccc;
aggregated-ether-options {
    lacp {
        active;
    }
}
unit 0;

[edit routing-instances L2VPN-AE-TEST]
instance-type l2vpn;
interface ae4.0;
vrf-target target:65543:100372;
protocols {
    l2vpn {
        encapsulation-type ethernet;
        site local {
            site-identifier 2;
            interface ae4.0 {
                remote-site-id 1;
            }
        }
    }
}

The AE has two links active and traffic is incoming from the CE on
both links.

So not very much to see. Any idea why the MX does not use both
outgoing links in the ae bundle?

Regards

Sebastian
