The main disadvantage of static routing is that it is a feasible means of maintaining only small routed networks. As a network grows, the administrative cost of maintaining static routes quickly outweighs the cost of implementing and maintaining a dynamic routing protocol. A second disadvantage of static routing is the lack of fault tolerance. If a route is improperly configured, connectivity is disrupted until the problem is diagnosed and fixed.

Off the Record On the exam, you might see static routes being used in a corporate LAN scenario, but in the real world they are used only when no other option is feasible. Maintaining static routes for real networks would just be too tedious and time-consuming. Not only would you have to spend time creating the static routes, but you would also need to perform all updates and troubleshooting manually.

Contention occurs when more than one operation, process, or worker thread attempts to access the same resource at the same time. Sometimes the resource is locked. Sometimes a resource such as disk I/O or memory comes under stress and a bottleneck occurs. Creating and dropping a large number of temporary tables and table variables can cause contention on metadata in tempdb. In SQL Server 2005, local temporary tables and table variables are cached to minimize metadata contention. However, for SQL Server to cache a table, no named constraints and no DDL operations (for example, CREATE INDEX and CREATE STATISTICS) can exist on the table after it is created. You can monitor the following performance counters for any unusual increase in temporary objects allocation:

In comparison, the RIP dynamic routing protocol, which essentially performs the same func] tion as static routes, is easy to install and requires almost no maintenance. For larger networks requiring the OSPF dynamic routing protocol, static routing is not even an option. Basically, the only time you should use static routes instead of RIP or OSPF is when a con] nection to a remote router is intermittent. In these cases, dynamic routing protocols cannot be used because they require routers to communicate every few seconds (30 for RIP, 10 for OSPF).

Module Module1 Sub Main() Dim myUser1 As GenericIdentity = New GenericIdentity( AHankin ) Dim myUser2 As GenericIdentity = New GenericIdentity( TAdams ) Dim myUser1Roles As String() = New String() {"IT", Users", "Administrators"} Dim myPrincipal1 As GenericPrincipal = New GenericPrincipal(myUser1, myUser1Roles) Dim myUser2Roles As String() = New String() {"Users"}

To prevent problems, you should consider the following design issues before you implement static routing.

Peripheral routers by definition have only one neighboring router. Found at the periph ery of networks, they connect the outer subnets of an organization to its network backbone. To simplify configuration, you should normally configure a peripheral router with a default route that points to its neighboring router. In Figure 9-16 shown earlier, Router C-B is a peripheral router. Its default route should therefore point to the neighboring router, Router B-A.

You should avoid configuring two neighboring routers with default routes that point to each other. A default route passes all traffic that is not on a directly connected network to a specified router. Two routers that have default routes pointing to each other will produce a routing loop for traffic with an unreachable destination.

New GenericPrincipal(myUser2, myUser2Roles)

In this practice, you use the Routing And Remote Access Server Setup Wizard on Computer1 to configure the Routing And Remote Access service for LAN routing.

In this exercise, you configure and enable the Routing And Remote Access service on Computer1. 1. From Computer1, log on to Domain1 as Administrator. 2. Open the Routing And Remote Access console by clicking Start, selecting Admin istrative Tools, and then clicking Routing And Remote Access. The Routing And Remote Access console opens. 3. In the console tree, right-click the COMPUTER1 (Local) node, and then click Configure And Enable Routing And Remote Access. The Routing And Remote Access Server Setup Wizard launches. 4. Click Next. The Configuration page appears. 5. Read all of the options available on this page. 6. Select the Custom Configuration option, and then click Next. 7. The Custom Configuration page appears. 8. Read all of the options available on this page, and then answer the following question: How many basic routing functions can be configured through this wizard
