Symptom
Problem description
Here there are no interfaces involved in BGP or BFD session going down instead it is the LC which is hosting the bfd session that is going down. Please note the interface/LC on which BGP neighbor is present is undisturbed. Moving the bfd session from one host LC to another is seamless.
This ddts is tracking the case of bfd timeout seen during LC hosting bfd session reload
Workaround
BFD will restore by itself
