nsf cisco & mpls ldp sync

[Lina Sami]

Hello,

in this guide: 

https://www.cisco.com/c/en/us/td/docs/ios/12_0s/feature/guide/fsldpsyn.html#wp1053852

i have found out that: The MPLS LDP-IGP Synchronization feature is not supported during the startup period if IGP NSF is configured.

My question is: Is there an exception or a benefit to have both configured together?

Oh, now i have understood correctly! I have overseen "during the startup period ". That mean they will work together After the NSF startup is complete.
