IP Infusion Enhances its Routing Suite with IS-ISv6 and CSPF Extensions for IS-ISv4

IP Infusion released version 5.2 of its ZebOS Advanced Routing Suite featuring new support for Intermediate Systems-to-Intermediate-Systems for IPv6 (IS-ISv6), as well as Constraint-based Shortest Path First (CSPF) for IS-ISv4 support. The IPv6 Intermediate System-to-Intermediate System (IS-ISv6) Module is based on link-state technology with two levels of hierarchy. It stores information about the state of links and uses that data to select paths. IS-ISv6 forwards packets directly over the underlying link-layer protocols using the Dijkstra algorithm to find the shortest path to the destination. The IS-ISv4 Constrained Shortest Path First (CSPF) extensions calculate an optimum explicit route (ER) based on the specified constraints, using Traffic Engineering Database (TED) and pre-existing LSPs. The resulting ER is used by a signaling protocol, such as RSVP-TE, to setup LSPs.
