The normal answer in Cisco land, even today, is to use Martini-draft
P2P pseudowires (either tag or port-based MPLS interconnects) which
will use tLDP for establishment, and should serve you very well
(especially at a port-based level) for a P2P service. In theory tLDP
could run in concert with SR-MPLS, but you might need to think
carefully about label allocation, or... [read on]

options (e.g. bpduguard, BUM rate-limits) as well as the ARP/ND
sponging/proxy facilities therein. For multipoint L2VPN, this should
be replacing VPLS now.
Realistically though, protection from storms is hardware dependent,
and making sure that the config is correct is only half of the battle.
I would consider not building L2VPNs for third parties where you don't
control the CE, realistically. Do they really need L2?
Tend to agree. We use Martini pw's in our network too. We have stayed
away from VPLS and EVPN, as we find out the most customers can
accomplish complex p2mp or mp2mp via IP instead of Ethernet.
