Hello, I have not had this problem in the past, and I have burned up a lot of time trying to troubleshoot this.
A couple of times, I have gotten everything working, but it fails again.
In this lab, i have a chain of 3750's, acting as switches (trunking for labs) -- but also L3 between the devices.
1. I never have a problem seeing the adjacent swrouters using CDP. 2. ....but I cannot ping the IP addresses of the directly connected interfaces.
As a result, the OSPF routing protocol fails.
If I cannot get this fixed, I am going to have to go to a rental lab (ccie).
Any ideas? Thanks.
