Internet News Internet Investing Internet Technology Windows Internet Tech. This is my first post to the forum, and I'd like to briefly introduce myself. Anyhow, here's my OSPF question. There are two fairly independently administered but highly-interconnected groups here.
All routers are Cisco.
Routers R1 and R3 speak BGP, handle external routes, and inject OSPF default routes into their respective stub areas. Routers R2 and R4 handle inter-area traffic and provide robustness in the event of an ABR outage. I haven't found anything that leads me to believe that it's not.
