[c-nsp] Incremental SFP (ISPF) - Provide any benefits "now"?

[CiscoNSP List]

Hi,


Quick question re ISPF - Seems to be a very old feature (Introduced 12.0?) that was more "efficient" than full SPF algorithm (Allows OSPF to converge faster)...but it appears Cisco are deprecating it, and I can only assume because it is no longer necessary on today's faster hardware?


Does anyone use it? Find it actually improves convergence?


Cheers
