I've have recently spotted this on an ios switch. With backup comparison, we were able to spot that the ace order in an acl was changed to permit ip any any. I'm also looking for more info on this.
Amazing work! I'm really a big fan of the booksprints releases; I wish there was a way to get my hands on a version on paper; I would adore if you guys can try to make a collab with ciscopress or so to make it on paper available to a wider audience.
