Very General BGP question

We are a growing, mulithomed ISP and have had continous problems with IP addresses every time we change upstream providers on either of our networks. We are interested in obtaining our own IP blocks from ARIN. It immediately came to out attention that the ARIN site says that smaller blocks might not be globally routed. Is BGP the answer to this difficulty. Can anyone refer me to general, introductory document on BGP routing?

Thanks!

Re: Very General BGP question

All ISPs get some block of addresses, which they reallocate to customers. Smaller blocks are not recommended to be routed because, they just increase the number of routes in the global routing table. Thats why ISPs summarise customer routes and advertise it to the internet check out ietf.org to get rfcs on bgp... or try reading Internetwork Routing Architectures by Bassam Halabi....its a good book
