George and others, 

AIS is introduced in the draft-fbb-mpls-tp-data-plane-00 (Section 2.1). 

Question: Is it Source LSR or any intermediate LSR to send AIS upon
detecting adjacent link failure? 

Same question goes to Link Down Indication. Is it the Source LSR who
indicates its adjacent link being Down? 

Thanks, Linda Dunbar
