This chapter describes the components of the following windows:
The Router Configuration window is used to access router configuration attributes. As there are numerous router related attributes, many windows can be displayed from actions initiated in the Router Configuration window. See "IP Configuration Windows" for detailed information about IP-related attributes and the corresponding windows displayed as a result of clicking on IP-related buttons. See "IPX Configuration Windows" for detailed information about IPX-related attributes and the corresponding windows displayed as a result of clicking on IPX-related buttons.
The following buttons are present in several windows. For brevity, they are described once here.
You display the Router Configuration window in one of the following ways:
See "Topology Window" for detailed information about the Topology window. See "Round Trip Path Window" for detailed information about the Round Trip Path window and "Find Device Window" for detailed information about the Find Device window. Tutorials pertaining to some of the features described in this chapter are provided in the Enterprise/Solver Connectivity Tools User's Guide.
A Router Configuration window, shown in Figure 8-1, is used to view and modify router and router interface attributes. Placing the cursor or clicking (if the mouse is set to click-to-focus mode) within a Router Configuration window highlights that router's icon in the Topology window if it is displayed.
This window's components are described in the following sections. See "General Window Components" for a description of the Context, Apply, Revert, Close, and Help buttons.

Click on this button to switch the context from the Router Configuration window to the IP Access List Summary window. A summary of the existing IP Access List numbers and the interfaces and/or routing algorithms they apply to are displayed in this window. See "IP Access List Summary Window" for a detailed description of the IP Access List Summary window components.
Click on this button to switch the context from the Router Configuration window to the IPX Routing Table window. Information about the routing table as computed in simulation are provided in the IPX Routing Table window. See "IPX Routing Table Window" for a detailed description of the IPX Routing Table window components.
Click on this button to switch the context from the Router Configuration window to the IPX Static Routes window. Information about the static routes configured for this router are provided in the IPX Static Routes window.
Click on this button to switch the context from the Router Configuration window to the IPX Routing Algorithms window. Information about the algorithms used to calculate the routing table are provided in the IPX Routing Algorithms window. See "RIP IPX Algorithm Window" for a detailed description of the IPX Routing Algorithms window components.
Click on this button to switch the context from the Router Configuration window to the Static SAP Table window. Information about the SAP Table entries are provided in the Static SAP Table window.
Click on this button to switch the context from the Router Configuration window to the IPX Access List Summary window. A summary of the existing IPX Access List numbers and the interfaces and/or routing algorithms they apply to are displayed in this window. See "IPX Access List Summary Window" for a detailed description of the IPX Access List Summary window components.
The Configuration Text window, shown in Figure 8-2, is displayed in one of the following manners:
This window displays a version of the router's configuration file currently understood by the Connectivity Tools, including any router attribute modifications you have made in a scenario. The purpose of this file is to more easily allow you to track the changes made to routers during "what-if" analysis.
| The router configuration information displayed in this text file is | Warningnot a usable configuration file for actual implementation in a router. It is a subset of the actual router configuration, as only those configuration commands that were parsed to build the baseline are included. It also does not include no commands. Certain parts of the configuration text file may be useful as is. If so, you can save the router configuration text file and cut and paste the changes into the actual router configuration file. |

This window's components are described in the following sections. See "General Window Components" for a description of the Close and Help buttons.
A version of the router configuration file, showing the commands modeled by the Connectivity Tools, is displayed in this pane. When using the Connectivity Baseliner, the contents of this file do not change. When using the Connectivity Solver, modifications you have made to the current router attributes through "what-if" scenarios are denoted by !!!!Changed appearing in this text file. For example, if you turn off the IP split horizon feature on an interface, the interface's split horizon entry in the router configuration file changes from ip split-horizon to no ip split-horizon. You can save the configuration text file for future reference.
!!!!Changed comment is inserted in the router's configuration text file. When you edit an existing access list row, a !!!!Changed comment does not appear in the configuration text file. However, the modified access list rule is actually inserted in the configuration text file.
The following limitations exist with the configuration text being displayed:
