Here is a better diagram:
Net A - OSPF Net B EIGRP
172.28.0.0
172.19.0.0 172.19.49-58.0 172.19.50.1
X-------------------------X------------------------X
RouterA Router B Router C
I don't understand the need for the 'no auto-summary' command. I have full
connectivity within the EIGRP network and I am not redistributing eigrp into
ospf. I use the static route on Router A to avoid the redistribution.
(Although the next thing I will probably try is redistributing EIGRP into
OSPF, cos I am out of ideas).
Also, is the metric really necessary for ospf. The default metric for an E2
route is 20, and there is only one route to NetB, so the lower the metric
the bettter?
The point of these changes is to prevent Network B from knowing anything
about network A, only how to get to it.
I should also mention that I have constructed the network in a lab and
everything works great, but I can't simulate the 1000 network ospf database,
possible routing loops and convergence time.
Thanks for the help so far,
Dion
