Configuring IP Routing (Layer 3)

 

 

 

 

 

 

Table 7-2.IP Global Configuration Parameters (Continued)

 

 

 

 

 

Parameter

Allows you to...

 

 

 

 

 

 

Route Preference

Describe the routing preferences set up according to the network

 

 

by Protocol

administrator’s preferences. These preferences are normally set up using a

 

 

 

system based on the most to least trust. For example, local routes are

 

 

 

normally considered to have more trust or a higher preference, while OSPF

 

 

 

external routes are considered to have less trust or a lower preference.

 

 

 

These preferences can be overridden, but careful consideration must be

 

 

 

given to how the preferences are set up.

 

 

 

 

 

 

Local Routes

Specify a preference value for local routes.

 

 

 

 

 

 

High-Preference

Specify a preference value for high-level static routes.

 

 

Static Routes

 

 

 

 

 

 

 

OSPF Intra-area

Specify an OSPF intra-area route. A lower number indicates a lower

 

 

Routes

preference for the path.

 

 

 

 

 

 

OSPF Inter-area

Specify inter-area paths to destinations in other OSPF areas. These are

 

 

Routes

discovered through the examination of received summary Link State

 

 

 

Advertisements (LSA). Enter a number to specify your path cost. A lower

 

 

 

number indicates a lower preference for the path.

 

 

 

 

 

 

OSPF External

Specify AS external paths to destinations external to the Autonomous

 

 

Routes

System. These are detected through the examination of received AS

 

 

 

external LSAs. Enter a number to specify your path cost (preference). A

 

 

 

lower number indicates a lower preference for the path.

 

 

 

 

 

 

RIP Routes

Specify RIP to use the hop count as a metric. Hence, to specify a preference

 

 

 

for a RIP route, you need to enter a lower number (path cost).

 

 

 

 

 

 

Low-Preference

Specify a preference value for low-level static routes.

Assigning IP Interfaces to the VLAN

After you have set up a VLAN and enabled IP Routing, create the IP interface that your VLAN and your subnet use to communicate with each other. After creating the IP interface, you assign it to the VLAN. If you need to create a new VLAN, refer to “Creating and Implementing VLANs” in Chapter 11.

To create a new IP interface and assign it to a VLAN:

1.In the IP Configuration section of the Web Agent window, click Interfaces. The IP Interfaces dialog box opens.

2.Click CREATE. The Add IP Interface dialog box opens.

3.In the Interface field, enter the Interface name.
