Priscilla, I can't think of anything that could have been broken by using the ip ospf priority command. Unless you've run into some sort of bug I'm guessing that there must be another issue. Were you playing around with the loopback addresses? Do you have any virtual links configured? I'm just wondering if you configured something that depended on a static router ID and by adding or changing a loopback you've confused one or two of the other routers.
You mentioned that the frame relay interface is configured as point-to-point. Is the opposite side configured the same way? It must be since you said the adjacencies are forming...nevermind. Hmm... Are the missing routes in the OSPF database, just not in the routing table? If so, check out this link: http://www.cisco.com/warp/public/104/26.html I can't think of any one thing that describes this issue but I'll keep pondering... John >>> "Priscilla Oppenheimer" 2/4/02 2:30:35 PM >>> Hi Group Study, Playing with IP OSPF priority to influence which router became the Designated Router (DR) caused routing problems for me in a recent bout with a lab exercise. Can anyone help me understand if I did something wrong? I have 2 routers on an Ethernet LAN. Both of them also have WAN connections to remote sites. R1 has a Frame Relay link to the corporate "cloud" via its S0 port. S0 is configured as "ip ospf network point-to-point." R2 has an ISDN link to yet another router, R3. This link is configured as an OSPF point-to-point demand circuit. R1 and R2 are connected via an Ethernet switch. My goal was to make sure R1 became the DR on Ethernet. Both routers have loopbacks, but R2's is higher, so to make sure R2 did not become the DR, I configured it with: ip ospf priority 0 R1 then did indeed become the DR on the Ethernet LAN because it was using the default priority 1. Now, finally to the question...... On the other side of the ISDN and across the Frame Relay cloud, I couldn't see the Ethernet LAN in the routing table. Routers formed adjacencies correctly and could reach most networks, but not that darn Ethernet LAN. R1 and R2 on the Ethernet LAN formed an adjacency and could see the rest of the internetwork. Could I have broken something by playing with the priority?? Thanks for your help.
