Peter,

Originally with ISO addressing the AFI identifies the assigning authority and the format of the address, however actually with IP only routers the AFI has no actual meaning, it is just a part of the AreaID, moreover most commonly an AFI of 49 is used as per the NSAP format standards.

I hope that I’ve been informative.

BR,
Mohammed Mahmoud.

@Rady,

ISIS is widely used in service provider networks and carriers, the protocol can scale very well and in the same time simple in implementation
