OMCR is supported only for IPoEv4/v6 subscribers. PPPoEv4/v6 subscriber hosts are not supported. However, non-synchronized PPPoE hosts can be hosted on the protecting node simultaneously with the protected IPoE subscribers. PPPoE PTA (locally terminated) non-synchronized subscribers and OMCR synchronized IPoE subscriber must not be configured under the same group-interfaces. On the other hand, non-synchronized PPPoE LAC sessions can be under the same group interface as the OMCR synchronized IPoE subscribers.
The recovery of PPPoE subscriber host in non-synchronized environment is based on the timeout of ppp-keepalives.
