Hi, we are in a process of linking ourselves with a business partner for database information sharing.
We are going to get a direct leased line between us and the partner.
my question is how are we going to control the routing to make sure that we don't see their network and they don't see ours? the reason being that we use same ranges. what is the best design for this application?
Please help

Hello Emmanuel,
routing can be performed using static routes to advertise the unique subnets for the DB exchange service.
if you use a dynamic protocol like RIP or EIGRP you can use distribute-list in order to accept only selected routes.
You may need to use NAT also and the suggestion is to divide NAT job on the two sides.
you may need to agree on two extranet ip subnets:
one to be used as source for packets leaving your network towards them.
one is used on the other side to change the source of ip addresses in their network.
in this way you can achieve connectivity.
Hope to help
