I have 02 domains in a forest. These domains are at 02 different sites interconnected thru T1. Domain A uses 100.100.101.0/16 subnet and domain B uses 100.100.103.0/16 subnet. Domain A has Cisco1700 router with 100.100.100.253/23 ip address for e0 and 10.10.1.2/30 for s0 interface. This router connects to domain B thru T1 on Cisco 2611 router on s0/1 with ip address 10.10.1.1/30. e0/0 interface on Cisco 2611 router has ip adress 100.100.103.1/24.
We have decided to move domain A to the same physical site as domain B eliminating T1 between Cisco 1700 and Cisco 2611 routers. How should I configure the s0 interface on 1700 router and s0/1 interface on 2611 router to ensure un-interrupted data flow. Thanks.
