[j-nsp] MPLS load balancing hash-key

No.

MPLS packets are hashed using only the MPLS hash key.  MPLS packets
are not further inspected to determine if the encapsulated data is
an IP packet or something else.

Similarly, IP packets are hashed using only the IP hash key.

Hi,

What will happen if I configure load-balancing with hash-key as
follows:

forwarding-options {
    hash-key {
        family inet {
            layer-3;
            layer-4;
        }
        family mpls {
            label-1;
            label-2;
        }
    }
}

Will the router take into account the IP layer when it receives
MPLS packet on ingress interface?
Thanks in advance,
Adam.
