Excerpts from David Coulson's message of Thu Nov 12 13:07:35 -0800 2009:
You could route /32s within your L3 environment, or maybe even leverage something like VPLS - Not sure of any TOR-level switches that MPLS pseudowire a port into a VPLS cloud though.
I was recently looking into this (top-of-rack VPLS PE box). Doesn't seem to be any obvious options, though the new Juniper MX80 sounds like it can do this. It's 2 RU, and looks like it can take a DPC card or comes in a fixed 48-port GigE variety. I like the idea of doing IP routing to a top-of-rack or edge device, but have found others to be skeptical. Are there any applications that absolutely *have* to sit on the same LAN/broadcast domain and can't be configured to use unicast or multicast IP? --j
