Here is my setup.
Main Router
P4 1.8GHz CPU with Intel Mobo (Custom Built)
256MB Ram
64M IDE Flash card
2 - 3Com 3c905XX ethernet cards
One of the remote routers
Dell Optiplex GX1 Desktop style system
P3 450MHz to 500MHz
128-256MB of Ram
64M IDE Flash card
2 - Routerboard24 4 port cards
I can setup OSPF on both of these machines. When the Routerboard24 card is part of ether1 to ether4 no ospf link is established between the routers. When I replace the Routerboard24 card with a Routerboard44 card everything works great, no problems. Any help would be great, thanks.
