Hello all. I am in the process of designing a network infrastructure for a DR scenario.
What I need to do is move some existing CIDR (/24) subnets to a new site and make sure all routing (connectivity for management from a third site) is correct.
Essentially I will be creating discontiguous subnets.
As an example:
Currently one 10.A.X.X/16 network with multiple /24 subnets exist in one location.
After the move the new DR location will contain 10.A.10.X/24, 10.A.11.X/24, 10.A.12.x/24 subnets and so on, for a total of about 40 subnets.
The existing location will still contain the rest of the subnets.
Right now the routing is static, I route based on the 10.A.X.X/16 address. And I want to avoid to have to create routes for every subnet that has moved to the new site and for the subnets that have remained at the old site.
I think the EIGRP would help in this situation. And I know that I can specify the EIGP not do subnet summarization...
Anyone had a similar scenario and what is the best way to simplify the routing situation.
Thank you very much.
