Task 2.1 - IOS Behavioral Issue??
I was running IOS 12.4(24)T8 on all of my IOS devices (thinking newest is best); but, after watching INE's advanced troubleshooting vSeminar, Brian Dennis specifically states about 5-10 minutes into the intro video to run 12.4(15)T on all routers and 12.2(44)SE on all of the 3560's (running 5 1841's, 1 3825, 4 3560's).
Anyway, on task 2.1, the OSPF peerings will never come up if you don't adjust the network type on the frame-relay to PTP on R3/4 and PTMP on R5. If you don't do that, it never sends the hello packet on the frame relay links to form the adjacency.
I thought that maybe a reboot would've fixed it, but that didn't seem to work either. What's even more interesting is that prior to the reboot (applying the beginning of the config after a 'write erase') the OSPF network type was "Broadcast"; however, after a 'wr mem' and a reboot, the OSPF network type was "NON_BROADCAST" - obviously requiring a network statement.
Has anybody else run into this?
