Hi all,
i'm new to this Cisco world so bare with me please. i'm trying to configure OSPF between two Cisco 2800 series and i'm unable to see the neighbor routers. the design is not fully completed since i'm waiting for my second ASA and ISP link but i'm trying to get as much done and configure both routers. i had bgp configured and working but removed it to try to isolate the issue. i will be adding it back.
here is brief of the topology i have and will be implementing. see attachment for a more detail drawing.
Thanks in advance for the help.
