Description (partial)

Multicast traffic over PPPoL2TP not working.

Symptom:
The issue occurs when multicast traffic has a Virtual-Access interface in its OIL. In this case, it's seen that IPV6 multicast traffic is dropped.

Conditions:
The Issue is only seen when the traffic flows from the Virtual Access interface to receivers connected downstream on the Dialer interface. Multicast traffic in the other direction is fine.
