[j-nsp] Ethernet OAM question?

[tim tiriche]

Hello,

I am trying to connect a Point-to-Point Ethernet Circuit via multiple
ethernet segments.
R1 - switchA - switchB - switchC - switchD - switchE - R2 (switches
are multiple providers)

Can i run link fault management between R1-R2 or is LFM only between
R1 - switchA?

What keepalives method i can use to detect a failure somewhere in the
provider and bring the R1-R2 physical link down.
Bring this link as AE and run LACP?

Regards,
Tim
