[j-nsp] ERP with switches not supporting ERP

[Bit Gossip]

Expert,
in a ring such as R1-r2-r3-R1 where, R1-r3 is the RPL and R1 is the RPL
owner and fully supporting ERP, while r2 and r3 don't understand ERP and
just forward transparently the ERP frames which are to mcast mac-address
01:19:a7:00:00:01; from an ERP perspective the ring is just R1-R1.
So will ERP works in a way that if R1-r2 goes down, R1 will detect it
and bring up the RPL R1-r3?
Thanks,
bit!
