Chapter 2. Router Node
The first dependent node is actually a new SP Switch Router Adapter in a router. This chapter offers more details about the implementation.
Section 2.1, “Overview” on page 5 gives you an overview of SP Switch Router. This is probably the best to get an impression what the GRF is good for. Also a functional- and a
More details about the underlaying Software and Hardware can be found in Section 2.2, “GRF Software” on page 18 and Section 2.3, “GRF Hardware” on page 24.
Section 2.4, “PSSP Enhancements” on page 40 describes the enhancements in the PSSP Software for the support of the dependent node.
Some planning considerations which should be considered can found in Section 2.5, “Planning for the GRF” on page 63 and Section 2.6, “Planning for the Dependent Node” on page 65.
2.1 Overview
The purpose of the SP Switch Router Adapter is to allow the GRF ("goes really fast"), manufactured by Ascend, to forward SP Switch IP traffic to other networks. The GRF was known as the High Performance Gateway Node (HPGN) during the development of the adapter. IBM remarkets models of the GRF that connect to the SP Switch as the SP Switch Router model 04S
Note: In the remainder of this book, we refer to the SP Switch Router as the GRF.
The distinguishing feature of the GRF, when compared with other routers, is that it has an SP Switch Router Adapter and therefore can connect directly to the SP Switch (see Figure 1 on page 6).
