Greetings, here is my problem that I am having, in the process of moving between providers and have both sets of addresses mapped in the network. Network Layout is like this: All routing is being done by OSPF, what I want is the clients that have not yet updated their equipment to be properly routed out their appropriate gateway. And the customers that have switched get routed out the new gateway. Any suggestions on getting the routing to work this way? I have tried static routes with routing marks on the Central Router for redirecting the new provers addresses to their gateway, leaving the OSPF default route in place to the old provider.
