I'm wondering if this is a trick question. My first thought is that if you only configure an IP address on the link then only IP will pass over the link. Without additional configuration this alone would stop IPX, AT, bridged traffic, etc. from crossing the link.
Another thought is that DLSw+ is IP, yet it carries bridged traffic. Do you want to stop that? Use an access list. The only other traffic then might be CDP, so use 'no cdp enable' on the BRI to turn that off. I suppose you wouldn't be able to stop someone from tunneling some other protocol in IP over the link but I don't think you're concerned about that. Am I making this harder than you intended? :-) Forgive me, I need more coffee and I have a cold.
