The Routes page (Network Analysis tab > Performance tab > History section > Routes) page provides a basic picture of the routing environment for the managed network, and for specific device groups. Click a device group in the Select Device Group panel to display information for the routing tables associated only with that device group.
Types: This table shows the number of routes as of 1 minute after midnight on the selected date, and the difference from the previous day (in the Diff column, which applies only in the current time period). Internal and External route designations are based on the CIDR list used during the discovery process.
Route Type History: This chart shows the number of routes over the 30 days before the selected date.
Protocols: This table shows the number of routes for each protocol type in the canonical network routing table discovered on the network. Discovered and tabulated route types include all the standard protocols, including BGP, Cisco IGRP, ICMP, IS-IS, Local, OSPF, Other, RIP, and Static routes.
Route Protocol History: This chart shows the number of routes for each protocol during the 30 days before the selected date. You can scrutinize significant shifts over time by choosing different dates and time periods through the date picker.
