Hi guys. I`m being tasked to add OSPF authentication to all our devices that use OSPF. I did some research and I know how to do it. The thing is, I'm not sure how I could do it in a timely manner... Also, how can I tell which interface is in which OSPF process? When I do a show ip ospf, it lists the processes and tells me how many interfaces are in the process but doesn't tell me which ones.
Is there a way to enter the md5 password at the area level instead of at the interface level? That would be much quicker and easier for me.
Yes, on multilayer switches it is possible to use the "interface range" command similarly to this:
interface range Gig0/1 - 30
ip ospf message-key 1 md5 xxxx
