1.What command(s) do i use?

3.tnx!

what are you trying to accomplish?

LIKE THIS:

>Step 3. Disable OSPF updates on the appropriate interfaces on both CENTRAL and BRANCH.

>Disable OSPF updates on all LAN interfaces and to ISP.

Q: HOW CAN I DISABLE OSPF UPDATES ON ALL LAN INTERFACES? I DON'T KNOW THE COMMAND(S)?

THNKS!

There is a command to disable OSPF on a specific interface, like this:

[code:1]
Router# conf t
Router(config)# int fa0/0
Router(config-if)# ip ospf shutdown[/code:1]

i'm using PT ver.5.2, and this is the result:

Router(config)#int f0/0
Router(config-if)#ip ospf shutdown


invalid input detected at '^' marker.--word "shutdown"is error.

The command seams NOT supported by packet tracer. Another way to do it is to create an extended ACL and block OSPF updates using it, something like this:

[code:1]Router(config)# access-list 101 deny ospf any any
Router(config)# access-list 101 permit ip any any[/code:1]

Then you can apply it on the interfaces using the ip access-group command.
