Chapter 31 OSPF Table 67 OSPF Interface (continued) LABEL DESCRIPTION Authentication Note: OSPF Interface(s) must use the same authentication method within the same area. Key ID Key Cost Priority Add Cancel Clear Index Network Area ID Authentication Key ID Cost Priority Delete Cancel Select an authentication method. Choices are Same-as-Area, None (default), Simple and MD5. To participate in an OSPF network, you must set the authentication method and/or password the same as the associated area. Select Same-as-Area to use the same authentication method within the area and set the related fields when necessary. Select None to disable authentication. This is the default setting. Select Simple and set the Key field to authenticate OSPF packets transmitted through this interface using simple password authentication. Select MD5 and set the Key ID and Key fields to authenticate OSPF packets transmitted through this interface using MD5 authentication. When you select MD5 in the Authentication field, specify the identification number of the authentication you want to use. When you select Simple in the Authentication field, enter a password eightcharacter long. Characters after the eighth character will be ignored. When you select MD5 in the Authentication field, enter a password 16-character long. The interface cost is used for calculating the routing table. Enter a number between 0 and 65535. The default interface cost is 15. The priority you assign to the interface is used in router elections to decide which router is going to be the Designated Router (DR) or the Backup Designated Router (BDR). You can assign a number between 0 and 255. A priority of 0 means that the router will not participate in router elections. Click Add to save your changes to the switch's run-time memory. The switch loses these changes if it is turned off or loses power, so use the Save link on the top navigation panel to save your changes to the non-volatile memory when you are done configuring. Click Cancel to start configuring the above fields again. Click Clear to set the above fields back to the factory defaults. This field displays the index number for an interface. This field displays the IP interface information. This field displays the area ID (that uses the format of an IP address in dotted decimal notation) of an area to associate the interface to that area. This field displays the authentication method used (Same-as-Area, None, Simple or MD5). When the Authentication field displays MD5, this field displays the identification number of the key used. This field displays the interface cost used for calculating the routing table. This field displays the priority for this OSPF interface. Click Delete to remove the selected entry from the summary table. Click Cancel to start configuring the above fields again. MS-7206 User's Guide 183

Authentication

Note: OSPF Interface(s) must use the same authentication method

within the same area.

Select an authentication method. Choices are

Same-as-Area

None

(default),

Simple

and

MD5

To participate in an OSPF network, you must set the authentication method and/or

password the same as the associated area.

Select

Same-as-Area

to use the same authentication method within the area and

set the related fields when necessary.

Select

None

to disable authentication. This is the default setting.

Select

Simple

and set the

Key

field to authenticate OSPF packets transmitted

through this interface using simple password authentication.

Select

MD5

and set the

Key ID

and

Key

fields to authenticate OSPF packets

transmitted through this interface using MD5 authentication.

Key ID

When you select

MD5

in the

Authentication

field, specify the identification number

of the authentication you want to use.

Key

When you select

Simple

in the

Authentication

field, enter a password eight-

character long. Characters after the eighth character will be ignored.

When you select

MD5

in the

Authentication

field, enter a password 16-character

long.

Cost

The interface cost is used for calculating the routing table.

Enter a number between

0 and 65535. The default interface cost is 15.

Priority

The priority you assign to the interface is used in router elections to decide which

router is going to be the Designated Router (DR) or the Backup Designated Router

(BDR). You can assign a number between 0 and 255. A priority of 0 means that the

router will not participate in router elections.

Add

Click

Add

to save your changes to the switch’s run-time memory. The switch loses

these changes if it is turned off or loses power, so use the

Save

link on the top

navigation panel to save your changes to the non-volatile memory when you are

done configuring.

Cancel

Click

Cancel

to start configuring the above fields again.

Clear

Click

Clear

to set the above fields back to the factory defaults.

Index

This field displays the index number for an interface.

Network

This field displays the IP interface information.

Area ID

This field displays the area ID (that uses the format of an IP address in dotted

decimal notation) of an area to associate the interface to that area.

Authentication

This field displays the authentication method used (

Same-as-Area

None

Simple

MD5

Key ID

When the

Authentication

field displays

MD5

, this field displays the identification

number of the key used.

Cost

This field displays the interface cost used for calculating the routing table.
