Disaster Recovery Solution with Duplicate / Floating IP Subnet

Wilson Samuel · ‎08-20-2008

Hi,

I have a situation where I need to have a Disaster Recovery Site with same IP Subnet that is of the main site across a WAN link using Routers.

I'm not sure of it now and not able to recall the name of the technology about it.

Any help would be greatly appreciated.

Kind Regards,

Wilson Samuel

Hi Wilson,

The technology you are after is called L2tpv3(Layer 2 tunnelling protocol V3). It will allow you to have the same IP subnet accross WAN links.

Hope that helps,

Andres
