Yes! We've been doing that in our datacenter networks, using FRR as the
BGP implementation on both switches (running Cumulus Linux) and hosts
(running Ubuntu GNU/Linux).  Works like a charm (as long as you don't
run any software that wants to mess with IP/MAC mappings).

Using FRR/Cumulus's nice BGP implementation with extensions like RFC
5549 and "BGP unnumbered", it's also very easy to configure.  You can
basically set it up so that you can connect any server to any non-empty
set of ports across all leaf switches, and it will just work and use all
the links with a single address per server (well, two in our case,
because we haven't managed to turn off IPv4 yet ;-).

Dinesh Dutt (ex-Cumulus) has written a book "BGP in the Data Center"
that explains this and other more traditional methods of connecting
servers to BGP-based datacenter networks.  I think it's available as a
free e-book from Cumulus, erm, I mean NVIDIA.
