I have had a paid 50 prefix account since the day BGPmon became available and helped two clients implement a 500 prefix license over the past 4 years. None will be buying Cisco Crosswork Network Insights, based on my recommendation.<o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:12.0pt;font-family:Helvetica;color:black'>I really don’t know where to begin since there is so much to dislike in this new GUI.

It was probably given to some GUI developer with a minimal understanding of what the users needed. How do I know this? Take for example the main configuration menu: <a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__crosswork.cisco.com_-23_configuration&d=DwMFaQ&c=WO-RGvefibhHBZq3fL85hQ&r=NEt1bAdOCtalVd4Ws0dvlC8LeF95Hl1p6yYgtTh8luM&m=-Pg3iXEKIpSalpxdI3kK4hQWV5_Hr-Y7HRREP8sUMKI&s=LpLEpR5n-GCVlOQvh6QMFxcJOYoVRfGYkxm_frBRInA&e=" target="_blank">https://crosswork.cisco.com/#/configuration</a> with the first tab of “prefixes”. On that page there is <b>no</b> mention of which ASN the prefix is associated with. That of course was fundamental in the BGPmon menu: <a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__portal.bgpmon.net_myprefixes.php&d=DwMFaQ&c=WO-RGvefibhHBZq3fL85hQ&r=NEt1bAdOCtalVd4Ws0dvlC8LeF95Hl1p6yYgtTh8luM&m=-Pg3iXEKIpSalpxdI3kK4hQWV5_Hr-Y7HRREP8sUMKI&s=nl1V8mfc-M_1XZ_zxBJWRSr89KDzOWuIPOMJIaAums0&e=" target="_blank">https://portal.bgpmon.net/myprefixes.php</a><o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:12.0pt;font-family:Helvetica;color:black'>Or take for example its “express configuration”, where you insert an ASN and it automatically finds all prefixes and creates a policy. But does it know the name of the ASN? Nope.
