BGP question

[trunolimit]

I thought BGP was a routing protocol. Routing protocols belong in the Network Layer of the OSI model correct? Well I was looking at wikipedia trying to learn a thing or 2 about BGP and it said it was an application layer protocol. Can someone explain to me how BGP is application layer.

The TCP/IP model, despite being similar, is not another name for the OSI model.
Why is HTTP not a layer 3 protocol? If you understand that, then you know the reason for BGP's exclusion.

so in the OSI BGP is network layer but in the TCP/IP it is application? I thought the only difference between the 2 was that in TCP/IP the application, presentation, and session layers were combined into one layer and the Data link and Physical layer were bunch up into one also.

I don't know much about HTTP so I don't know why it's not considered layer 3 other than the fact that layer 3 deals with packets only addressed with IP address. HTTP from what I know deals with applications that the end user interacts with. "DATA"
