Network design - switches in a stack over a PTP link
Hi,
I have started work at a new company and come across a network design that is in place.
I have not familiar with this so please let me know if it is normal or not and why.
There are two sites. Lets call them site A and site B.
The sites are linked together using PTP links at both sites.
Everyone at site B connects back to site A over the PTP Links for internet access.
Earlier today, I connected to a switch virtual stack at site A and noticed there were switches from the site B in this virtual stack.
Shouldn't site A's switches be in their own virtual stack and site B's in their own virtual stack irrespective of the internet link.

I assume you're talking about clustering? Something like: http://www.cisco.com/c/en/us/support/docs/switches/catalyst-2900-xl-series-switches/4085-61.html
In my opinion that shouldn't be an issue (assuming the PTP link is stable and doesn't give you much down time). I can image that this was set up with easy of management in mind. As long as you have a standby command switch on the other end (command switch is at site A and a standby command switch is at site B), I don't see any problems with this specific setup.
Of course it is a choice of the administrator to determine what works best for him/her and the company (in this case: you).

Yes clustering. But clustering across a WAN seems odd to me.

Thanks
I would also be a tremendous help to know what make/model switches you're talking about.
