[Stuck with OSPF] [Packet Tracer] Cannot connect two discontiguous area 0s with virtual link

[Jeff_T1985]

Hi guys,

I bet lots of you are about to sit in front of TV for super bowl as I'm about to. However, I really want to be able to troubleshoot this CCNA lab problem before that. Help me if you can, please.

So here is the problem:

In the following topology, the area 0 of OSPF is discontinuous and between them there is an area 14. What I'm trying to do is to set up a virtual link to connect them. I've done the configurations on ASBR 1 and ABR 4 accordingly.

The IP connectivity between ASBR 1 and ABR 4 is just fine (the routers can ping one another) and the virtual link setting also seems like alright. However, the adjacency between the two routers has never been formed.

Output of the show run command on ABR 4 is as follows:

   router ospf 100

   log-adjacency-changes

   area 14 virtual-link 1.1.1.1

   network 155.1.34.0 0.0.0.255 area 0

   network 155.1.14.0 0.0.0.255 area 14

   network 155.1.45.0 0.0.0.255 area 45

   network 150.1.104.0 0.0.0.255 area 104

Output of the show run command on ASBR 1 is as follows:

   router ospf 100

   log-adjacency-changes

   area 14 virtual-link 4.4.4.4

   network 155.1.12.0 0.0.0.255 area 0

   network 155.1.14.0 0.0.0.255 area 14

   network 150.1.101.0 0.0.0.255 area 101

The original PKT file is also attached.

Hi.

I do realize this is an old question but I thought it was interesting and I took a look at it.

R1 did not have EIGRP as the topology said, so I fixed that and redistribution to and from OSPF.

ASBR1 did not have EIGRP either. The main problem is that OSPF did not want to work over the Frame-relay cloud. After forcing S0/0/0 to think it is a ospf point-to-point instead of broadcast(Frame-relay is NMBA), it started working.

Additional commands:
R1:
configure terminal
router eigrp 1
network 155.1.11.0 0.0.0.255
redistribute ospf 100 metric 100 10 255 1 1500

router ospf 100
redistribute eigrp 1 subnets

ASBR1:
configure terminal
interface serial 0/0/0
ip ospf network point-to-point

router eigrp 1
network 155.1.11.0 0.0.0.255
redistribute ospf 100 metric 100 10 255 1 1500

router ospf 100
redistribute eigrp 1 subnets

ASBR4:
configure terminal
interface serial 0/0/0
ip ospf network point-to-point
