OSPFv3 AF Authentication is finally fixed!
Unless you are a regular follower of this blog, you may not have heard that Cisco’s OSPFv3 with Address Families (AF) Authentication support was broken. By broken I mean it took down OSPFv3 adjacencies. Not good. Read here for that article. Anyway, I have been using the IOS-XE version 3.10.01S for about 2 months now on a production network with authentication enabled and not a single issue. So if you are reading this: IOS-XE 3.10.01S is the fixed version. If you use OPSFv3 AF and have an ASR don’t use anything less than 3.10.01S. Thanks for reading!
