DESCRIPTION

 

 

Distance

Enter a number from 10 to 255 to specify the administrative distance that is

 

 

 

assigned to routes learned by OSPF.

 

 

 

The lower the administrative distance value is, the more preferable the

 

 

 

routing protocol is. See Section 36.1.1 on page 327 for more information

 

 

 

about administrative distance.

 

 

 

Note: You cannot set two routing protocols to have the same

 

 

 

administrative distance.

 

 

 

 

 

 

Apply

Click Apply to save your changes to the Switch’s run-time memory. The

link on the top navigation panel to save your changes to the non-volatile

 

 

 

memory when you are done configuring.

 

 

 

 

 

 

Cancel

Click Cancel to begin configuring this screen afresh.
