difference between show ip interface brief and show protocols?

HiWhat is the difference between show ip interface brief and show protocols?

sh ip int br - Lists the interfaces and their IP Addresses and States. It's a quick way to find the State (UP/UP, UP/DOWN, ADMINISTRATIVELY DOWN/DOWN) of one or more interfaces and what their IPv4 Addresses are (you would use show ipv6 interfaces brief if you wanted to see what their IPv6 Addresses were).

[EDIT] sh prot - This appears to just give the same basic information formatted differently. I noticed one major addition: subnet mask (in CIDR Format). I would normally use sh int Fa0/0, but this would work also.

[This is what I was thinking of] sh ip prot - This command gives alot more information. Specifically, it includes information on what routing protocols are in use and what networks are included, etc...You would use show protocols to resolve issues with routing protocols. Though, it does include other info.

I was thinking of show ip protocols.
