Load-balancing on ASR 920 and ASR 903 RSP3

I need to understand how MPLS traffic is load balanced over:

1. Port-channels

2. ECMP

In Port-Channels, I see only

ASR920(config)#port-channel load-balance-hash-algo ?
dst-ip Destination IP
dst-mac Destination MAC
src-dst-ip Source XOR Destination IP Addr
src-dst-mac Source XOR Destination MAC
src-ip Source IP
src-mac Source MAC

Does that mean that for MPLS traffic the only load-balancing value is src/dst mac?

For ECMP, I couldn't find any document describing details on which label in stack is used for load balancing hash.

For XR, there is a good doc

https://supportforums.cisco.com/document/111291/asr9000xr-load-balancing-architecture-and-characteristics

describing that ECMP and BE load hashing algorithms are the same and if label stack is <=4 then balancing is based on even tcp/udp ports, while for label stack >4 balancing is on inner-most label.

Is there something similar for ASR 920/903?

I have the same question. What parameter to set for MPLS balancing?
