[rbak-nsp] Link Group - Access with PPPoE

[Brent]

Yeah...that's not in my docs for 6.1.3.8, and doesn’t work either.  Must be
a new feature.

Hi Brent,

>From documentation:

"An access LAG can be configured in either non-economical or
economical mode. The economical mode reduces the SmartEdge router
resources used by the access link group, allowing more of these
resources to become available to other applications. In non-economical
mode (the default), circuit information on active ports is replicated
on all standby ports. After an active port fails, no packets are lost
when the standby port becomes active. In economical mode, which must
be explicitly configured, the circuit information for 802.1Q single-
or double-encapsulated (Q-in-Q) circuits on active ports is not
replicated on the standby ports. After an active port fails and its
standby port becomes active, a small number of packets on these
circuits are lost in the transition. Circuit information on IPoE- (the
default) or PPPoE-encapsulated circuits is replicated on all standby
ports regardless of mode."

Try to use "link-group ppp1 access economical"
