[j-nsp] Inter-racks switch routing recommended practice

Tue Jun 4 22:24:56 EDT 2013

Hi,

I'm building an infrastructure which comprises of a few tens of racks with Hadoop, Supermicro MicroCloud and whatnot running. Each rack probably will have EX4200 or EX3300 ToR switch, individually at the moment, not VC-chained. These switches will have a couple of EX4550 aggregating the circuits.

My question is what would be the best routing protocol in this kind of scenario? 

I'm thinking multi-areas OSPF/v3 but would a flat OSPF area 0 topology with BGP make more sense? I don't have a lot of exposure in dense datacenter routing so I'm bringing the conventional WAN routing thinking cap into the picture.

Thanks.
