IEEE 802 defines Ethernet-like networks.  Please explain how you want to
mix layer 3 into this.

FWIW, yes, link aggregation between Foundry and Juniper or Cisco
generally works, although almost nobody implements the nice parts of
LACP (the ability to move flows to another link in a bundle).

isn't possible with aggregation.
