Hi,
I was playing with cciebootcamp lab 1 and noticed that the OSPF area virtual-li
nk through area 3 provided router 4 with routes from area 0 but the routes in a
rea 44 didn't get back into the area 0 routers. It appeared as if r3 and r4 whe
re happy neighbors.
Your thoughts/feedback would be greatly appreciated.
Here are router 3 and router 4's configs ++.
Thanks,
-Derek
