NOTES:
1. VPLS service, SDP to SDP: Test has been performed only for VC label variation with the 
same Tunnel label.
2. In the LSR case, incoming labels are used for hashing. 
3. ‘Learnt’ wherever mentioned corresponds to Destination MAC. 
4. Source/Destination MAC refer to ‘Customer Source/Destination MACs’ unless otherwise 
specified. 
5. ‘service_id’ refers to the service id of the egressing VPLS/EPIPE/IES/VPRN service.
6. ‘lag_index’ refers to the Lag-IfIndex of the egressing lag.
7. 'encap_value' and 'service_vlan' are based on the inner/outer VLAN values of the 
egressing LAG SAP.
8. 'sap_index' is a value assigned uniquely for each SAP internally.
