Symptom: Transit L2VPN traffic is not load-shared between egress members on L3 lag when received on ingress with 3xMPLS labels - [ExpNull - LDP][BGP][L2VPN] [L2VPN Payload]. There are no issue: - for L3VPN payload with 3xMPLS labels - when payload has only 2xMPLS labels (LDP signals ImpNull) Adding control-word or FAT label does not helps. Conditions: NCS5500 performs IPv4 LU next-hop self and signals ExpNull for own Loopback.
