Redundancy over VPN (or on an another network)

[mcezmi]

Dear Guys,

I like to ask something interesting; I have a two ws5100, working in a redundant manner and 52 access ports in the group, some access ports has been connected via Layer 2, and some access ports done by adaptive AP5131 in remote location, via layer3 ip connection

I need a disaster recovery plan, I want to set up a new ws5100 in a remote location, they can reach them only via layer 3 (can ping each other), but not a layer2 connection. does ws5100 can work in this network?

I need your good informations

regards

Well my reply just got deleted so I'm bummed about that...

The WS5100 can only adopt 48 APs at a time so you are already beyond N+1 redundancy. You would probably be better off adding an additional WS5100 to your existing cluster so you can have N+1 redundancy. I can't envision a scenario where both my WS5100s would be down yet I would be able to connect to a remote network (or VPN). I connect my WS5100s to completely independent distribution switches and power sources to as to provide maximum redundancy between the two. You would probably be best served looking to improve the local network rather than trying to run the wireless from a remote network, you WLANs would also need to be terminated in a different VLAN or Layer 3 IP network so you'd also have that challenge.

Cheers!
