No Stretch

Disaster Recovery Faking, Take Two.

That is why you don’t use stretched VLANs. MBA types (and poor infrastucture engineers) say, “But it’s the same!” Sure, it’s the same and that’s the whole damn problem. Making things “the same” in a disaster recovery scenario is not what you are going for.

Routing and DNS exist for a reason, and they work. Freakin’ use them. All of this layer 2 stretched across half the continent means a world of pain when you actually need anything to work. Looks pretty on paper and to the MBAs, but in practice your DR becomes all disaster and no recovery.

And just wait till spanning tree has a problem and it’s all layer 2. That’ll be a whole other level of pain for you to enjoy!
