I have a database LAN connected to 2 WAN networks and dedicated fiber link into a mainframe. The database LAN is made up of a Cisco 4000 layer2 switch with no VLANs and one subnet 10.0.6.x ...
WAN 1 is extranet type and i control the router with subnets in the 172.x.x.x range. All routing is static.
WAN 2 is connected to internalWAN and the router is under the WAN admins with OSPF enabeld on it as the entire internal-WAN is OSPF enabled.
The dedicated mainframe connection is is on subnet 10.0.6.x as is my entire database LAN.
The mainframe is also connected to the internal-WAN via other ethernet cards into the WAN backbone/Cisco 7500/Cisco 6500 ...
After we turn-on the router connected to internal-wan and after 15 minutes, when we TRACERT to any of the windows2003 servers from the same LAN the path it takes is through the router and not directly as should be. After another 15 minutes or so, our SAN box gets disconnected and all servers never see each other....
How can i stop the win2003 servers from accepting externaly advertised routes or OSPF stuff ...
