Hi Robert,

Apologies for the shortcut. If you’re asking if this changes the number of LSPs in the network, it does not. The goal is to consolidate existing LSPs together. > So assume there are two ingress nodes and two spine nodes.

Both make the decision independently. That would be either poor path computation or colossally bad luck. Presumably Ingress_1 has decided to move traffic for a good reason, based on the available data. Even with make-before-break, latencies change and can be performance impacting, so moving traffic is never done lightly. For Ingress_2 to look at the same state of the network and make the opposite decision strongly suggests a bug in its path computation logic. If the path computations are not synchronized, then Ingress_2 would see the results of Ingress_1’s action, providing further data to Ingress_2’s computation. > Q1 - How is this helping to put one of the spine's ingress line card to sleep > (provided there is no demand which requires to run both ingress line cards on > both spines) That is out of scope for this document. Our job is to simply remove the LSPs from the path that should be placed in sleep. Further mechanisms are required. > Q2 - Once the traffic is moved (of course in make-before-break) fashion who > will trigger given line cards to go to sleep ?

Some of these may be implementation dependent. Regardless, these are out of scope for this document and LSR.
