Re: OT: Building Scalable Data Centers: BGP is the Better IGP

Petr,

Very interesting stuff. Would you mind a couple questions?

1. At what scale does this become viable. I realize you are dealing with a
massive data center, would it be appropriate for a data center with only
100 TOR switches or even 10 TOR?

2. Are you doing virtualization that needs to vmotion or otherwise have
layer 2 adjacency across the racks? If so are you doing some network
overlay such as VxLAN?

3. Is the configuration management something home grown or are you using
a commercial product?

Thank you,

Marc
