Description (partial)

Symptom:
if 'l2protocol-tunnel' command is configured on an nni port, REP ALT port egresses l2pt packet even when in blocking state.

Conditions:
The REP ALT port, after REP convergence must be in blocking state and should not egress any packet. When 'l2protocol-tunnel'  is configured on an nni this happens. The issue is not seen without this config.
