MPLS and Traffic Engineering - Testing and Interoperability

IP Infusion's ZebOSTM Advanced Routing Suite (ARS) is a platform-independent software package that supports IPv4, IPv6, and MPLS-based routing protocols for BGP, OSPF, IS-IS, and RIP. This report describes IP Infusion's MPLS testing and interoperability.

ZebOS supports multiprotocol label switching (MPLS) through the label distribution protocol (LDP), which provides a crucial platform for BGP-VPN (Virtual Private Network) and Traffic Engineering. Full Traffic Engineering support is by way of the OSPF-TE, RSVP-TE, CSPF, and CR-LDP modules.

Because all ZebOS software is a critical component in routing and switching platforms, IP Infusion devotes a substantial amount of time and resources to the testing cycle of each development release, including full functional testing and extensive combinatorial testing in Multiple Instance environments, Redundancy environments, and Virtual Router operation. This paper discusses IP Infusion's MPLS/TE/VPN testing methodology and outlines in detail each phase of our test cycle.
