Has anyone ever heard of a multi-homed enterprise not running bgp with either of 2 providers, but instead, each provider statically routes a block to their common customer and also each originates this block in BGP? One of the ISP's in this case owns the block and has even provided a letter of authorization to the other, allowing them to announce it in BGP as well. I had personally never heard of this and am curious if this is a common practice
I have seen it quite often. It allows an enterprise to be multihomed w/o getting PI or PA address space so they are usually pretty happy with it.
as well as if this would potentially create any problems by 2 Autonomous Systems both originating the same prefix.
AFAIR prefixes can be originated by more than one AS so there shouldn't be any issues. -- SY, Jen Linkova aka Furry
