Configure OSPF routing on all three routers. Use process ID 1. Disable OSPF updates on appropriate interfaces.
Configure OSPF MD5 authentication between R1, R2, and R3 using 1 as the key value and a cisco123 as the password.
Look under the Config tab for the TFTP server to determine the name of the newer Cisco IOS image. Then copy the newer image to flash on R2.
Verify that the new image is loaded in RAM.
could someone please help me
im really stuck i have completly forgotten everything
What about revising your stuff if you forgot everything ?we can give you the solution but then you won't learn anything if we do this.
At least try to configure something and if it doesn't work then show us your lab and we'll tell you how to find out why it is not working, this way you will learn not by being fed configuration commands without any explanation.
