Configuring Static Routing

Exam: Microsoft 70-649 - TS: Upgrading Your MCSE on Windows Server 2003 to Windows Server 2008, Technology Specialist


On most of the networks configuration of client computers must be done using a single default gateway. A single default gateway is used for sending and receiving all communications to the subnet. For the purposes of redundancy, network administrators may decide to place two default gateways on a single subnet. Irrespective of the default gateway, configuring static routing on a single subnet is not required. Configuration of the default gateways on the hosts can be done manually or by using a standard network configuration technique like the DHCP.

Configuring static routing is mandatory in case a computer brings into use different routers for communicating with different remote networks. The figure given below illustrates a network with static routing.

Static configuration can be performed using the route command line tool.

Using the Route Command

The route command allows examination and configuration of static routing from a command prompt. The route print command allows viewing the routing table. The command allows viewing the route tables for both IPv4 and IPv6.

For the purposes of convenience the output received from the command is split. The figures illustrated below depicts both the routing tables.

IPv6 Route Table

The destination networks are listed in the routing table that are accessed by the interface or the router. Particular details can be used for interpreting the routing table. Some examples of netmasks and what they depict are illustrated in the table below.

Netmask What it Depicts.
0.0.0.0 Depicts IP address of the default gateway
255.255.255.255 Depicts identify an interface
127.0.0.0 or 127.0.0.1 Depicts loopback interface.
224.0.0.0 Depicts a multicast address

IPv4 Route Attributes

IPv6 attributes can be categorized as:

  • Routes with a 128-bit prefix length - These are host routes for particular IPv6 destination.
  • Routes with a 64-bit prefix length - These are subnets representing locally attached subnets.
  • ::/0 routes - these are default routes.
  • ff00::/8 routes - these are for multicast traffic.

Configuring Static Routing with Routing and Remote Access

Once the Network Policy and Access Services server role are installed, the IP routing table can be viewed by clicking on Roles\Network Policy and AccessServices\Routing And Remote Access\IPv4\Static Routes. This has to be followed by selecting Show IP Routing Table. Routing And Remote Access allows displaying the static routing table.
