From the Layer 3 IP Networking folder, open the OSPF folder and click on the OSPF General

Setting link. To enable OSPF, first supply an

OSPF Rout ID

(see below), select

Enabled

from the

State

drop-down menu and click the

Apply

button.

Figure 4- 61. OSPF General Setup window

The following parameters are used for general OSPF configuration:

Parameter

Description

OSPF Route ID

A 32-bit number (in the same format as an IP address

−

xxx.xxx.xxx.xxx)

that uniquely identifies the switch in the OSPF domain.

It is common to

assign the highest IP address assigned to the switch (router).

In this case, it

would be 10.255.255.255, but any unique 32-bit number will do.

If 0.0.0.0 is

entered, the highest IP address assigned to the switch will become the

OSPF Route ID.

Current Route ID

Displays the OSPF Route ID currently in use by the switch.

This Route ID is

displayed as a convenience to the user when changing the switch’s OSPF

Route ID.

State

Allows OSPF to be enabled or disabled globally on the switch without

changing the OSPF configuration.

OSPF Area Setting

This menu allows the configuration of OSPF Area IDs and to designate these areas as either

Normal

or

Stub

.

Normal OSPF areas allow Link-State Database (LSDB) advertisements of

routes to networks that are external to the area, Stub areas do not allow the LSDB

advertisement of external routes.

Stub areas use a default summary external route (0.0.0.0 or

Area 0) to reach external destinations.

To set up an OSPF Area configuration click the

OSPF Area Settings

link to open the

following dialog box:

Figure 4- 62. OSPF Area Settings window

To add an OSPF Area to the table, type a unique

Area ID

(see below) select the

Type

from

the drop-down menu. For a Stub type, choose

Enabled

or

Disabled

from the

Stub Import

Summary LSA

drop-down menu and determine the

Stub Default Cost

. Click the

Add/Modify

button to add the Area ID set to the table Table.

To remove an Area ID configuration set, simply click the

X

in the

Delete

column for the

configuration.

To change an existing set in the list, type the Area ID of the set you want to change, make the

changes and click the

Add/Modify

button. The modified OSPF Area ID will appear in the

table.

See the parameter descriptions below for information on the OSPF Area ID setting.

The Area ID settings are as follows:

Parameter

Description

Area ID

A 32-bit number in the form of an IP address (xxx.xxx.xxx.xxx) that

uniquely identifies the OSPF area in the OSPF domain.

Type

This field can be toggled between Normal and Stub using the space bar.

When it is toggled to Stub, additional fields appear

−

Stub Import Summary

LSA, and Default Cost.

Stub Import

Summary LSA

Displays whether or not the selected Area will allow Summary Link-State

Advertisements (Summary LSAs) to be imported into the area from other

areas.

Stub Default Cost

Displays the default cost for the route to the stub of between 0 and 65,535.

The default is 0.

OSPF Interface Configuration

To set up OSPF interfaces, click the OSPF Interface Settings link to view OSPF settings for

existing IP interfaces. If there are no IP interfaces configured (besides the default System

interface), only the System interface settings will appear listed. To change settings for in IP

interface, click on the hyperlinked name of the interface to see the configuration menu for that

interface.

Figure 4- 65. Edit OSPF Interface Settings menu

Configure each IP interface individually using the OSPF Interface Settings – Edit menu. Click

the

Apply

button when you have entered the settings. The new configuration appears listed in

the OSPF Interface Settings table. To return to the OSPF Interface Settings table, click the

Show All OSPF Interface Entries

link.

OSPF interface settings are described below.

Some OSPF interface settings require previously configured OSPF settings. Read the

descriptions below for details.

Parameter

Description

Interface Name

Displays the of an IP interface previously configured on the switch.

Area ID

Allows the entry of an OSPF Area ID configured above.

Router Priority

Allows the entry of a number between 0 and 255 representing the OSPF

priority of the selected area.

If a Router Priority of 0 is selected, the switch

cannot be elected as the Designated Router for the network.

Hello Interval

Allows the specification of the interval between the transmission of OSPF

Hello packets, in seconds.

Between 5 and 65535 seconds can be specified.

The Hello Interval, Dead Interval, Authorization Type, and Authorization Key

should be the same for all routers on the same network.

Page 130 / 216

112

Dead Interval

Allows the specification of the length of time between the receipt of Hello

packets from a neighbor router before the selected area declares that router

down.

An interval between 5 and 65535 seconds can be specified.

The

Dead Interval must be evenly divisible by the Hello Interval.

State

Allows the OSPF interface to be disabled for the selected area without

changing the configuration for that area.

Auth Type

This field can be toggled between None, Simple, and MD5 using the space

bar.

This allows a choice of authorization schemes for OSPF packets that

may be exchanged over the OSPF routing domain.

None specifies no

authorization.

Simple uses a simple password to determine if the packets

are from an authorized OSPF router.

When Simple is selected, the Auth

Key:[

] field allows the entry of a 5 character password that must be the

same as a password configured on a neighbor OSPF router.

MD5 uses a

cryptographic key entered in the MD5 Key Table Configuration menu.

When MD5 is selected, the Auth Key ID:[

] field allows the specification of

the Key ID as defined in the MD5 configuration above.

This must be the

same MD5 Key as used by the neighboring router.

Auth. Key ID

Enter a Key ID of up to 5 characters to set the Auth. Key ID for either the

Simple Auth Type or the MD5 Auth Type, as specified in the previous

parameter.

Metric

This field allows the entry of a number between 1 and 65,535 that is

representative of the OSPF cost of reaching the selected OSPF interface.

The default metric is 1.

OSPF Virtual Interface Settings

Click the OSPF Virtual Interface Settings link to view the current OSPF virtual interface

settings. There are not virtual interface settings configured by default, so the first time this

table is viewed there will be not interfaces listed. To add a new OSPF virtual interface

configuration set to the table, click the

Add

button. A new menu appears (see below). To

change an existing configuration, click on the hyperlinked Transit Area ID for the set you

want to change. The menu to modify an existing set is the same as the menu used to add a new

one. To eliminate an existing configuration, click the

X

in the Delete column for the

configuration being removed.

Figure 4- 66. OSPF Virtual Interface Configuration

The status of the virtual interface appears (Up or Down) in the

Status

column.
