RE: OSPF and frame relay issues
Roberts already done that. He has his neighbor statements in and put the
"ip ospf priority 0" on R4 and R5's Serial Interface. This seems like an
inverse ARP issue. It's easy to fix with map statements but the
instructions say you can't use them.

router ospf 9

do the same on routers 4 and 5 with neighbor statements
back to router 3.

RE: OSPF and frame relay issues
This brings to mind a question I have about the neighbor priority statement. According to the Doc CD, the default value for neighbor priority is 0 I have on a couple of recent labs entered neighbor a.b.c.d and when doing a show run seen the priority 1 added to the end of the line I have also specifically entered neighbor a.b.c.d priority 0 and done a show run only to see the priority 1 tagged on the end. Has anyone else seen this phenomenon?

RE: OSPF and frame relay issues
Yes I have noticed that also. Though I just assumed it was a new feature much like setting tunnel MTU larger than the physical interface and sending packets with the df bit across :) I was however able to set the priority to 0 on the line by setting it on the interface and not with the neighbor command. This was confirmed to me when I did a "show ip ospf int" and the priority was correct. I did notice when trying to use the neighbor statement that in some routers it never even showed the priority had been changed nor did the command appear in my configs. I then decided to resort to the interface level command which apparently worked. One of those little things that bite...
