Hello Sandy, >How would you identify versions on those sessions which are down? Are you assuming the ToR might cache the information after the lifetime of the session? That’s probably quite implementation specific assumption and I probably wouldn’t bank on it being there. Good point. This can be reflected in logs or can be stored in peer's cache (but I'm not sure the latter is the right solution). Another use case would be like checking why some routes are not announced from random hosts? Even more, bundling this information together with FQDN capability would open a bigger picture of what's going on in your network.
