Does G2 series support load sharing based on inner L3 filds in the MPLS terminated packet?

Dear colleagues!
Does G2 series support load sharing based on inner L3 filds in the MPLS terminated packet?

Hello Alexander,

As far as I remember it is supported with algorithm "custom", even non-terminated MPLS packets are hashing with the following rules:

For L3 payload (i.e. not VPLS or VPWS), the IP source and dest addresses and the labels are used for hashing.
If the payload is VPLS/VPWS, only the labels are used for hashing. Since these have an inner L2 frame, the hardware can’t look that deep inside to see the L3 fields.

Best Regards,
Nikolay

Hello Nikolay!

It is true for G1 series switches.
But in the documentation on 30th version of XOS we can see:

Custom Algorithms...
* MPLS packets—Uses the top, second, and reserved labels and the source and destination IP addresses.
