Micro-loop DT
Eliminated:
Incremental cost change
Multiple convergence cycles per topo event
Excessively long convergence: O(h)
Sync’ed FIB installation
Tight synchronization (within 10ms) at the LC level required
Puts strong constrains on implementations (clock resolution, timer accuracy)
Service dependency on NTP
Operational concerns (“is my network sync’ed?”, “what happened?”)
