Solved SVI OSPF adjacency

---

In Lab Interconnecting Cisco Networking Devices (ICND2 v3.0)
Configure Verify and Troubleshoot Multi Area OSPFv2 for IPv4
Exercise 2 - Configuring Area 2

Step 1
it says right after the configurations
"Syslog messages appear that indicate adjacencies have formed between NYCORE2 and NYEDGE1 and NYEDGE2."

Looking at the diagram and configurations; it seems to me it that the adjancencies should be between NYCORE2 and NYEDGE2 and NYCORE1 but that is not what is happening.

thanks

Is it because they are SVI? or DROTHER? or 2way?

also is SVI interfaces form only a 2way adjacencies?

After the configurations of Step1, I see the following.

"After several seconds you should see new adjacencies being formed with NYEDGE1 and NYEDGE2 on the VLAN 1 interface."

Also NYCORE1 logs

*Mar  1 00:13:21.304: %OSPF-5-ADJCHG: Process 1, Nbr 192.168.16.1 on Vlan1 from LOADING to FULL, Loading Done

*Mar  1 00:13:21.304: %OSPF-5-ADJCHG: Process 1, Nbr 192.168.16.2 on Vlan1 from LOADING to FULL, Loading Done

So I'm not sure why there is a disparity in what you're seeing.

hm. I'm assuming you may have to check your configuration. I see you mention NYCORE2, but by step 1 the NYCORE2 switch is pre-configured.

So...

NYCORE1#show ip ospf neigh

Neighbor ID     Pri   State           Dead Time   Address         Interface
192.168.16.1      1   FULL/BDR        00:00:37    192.168.16.1    Vlan1 (NYEDGE1)
192.168.16.2      1   FULL/DR         00:00:32    192.168.16.2    Vlan1 (NYEDGE2)
192.168.33.18     1   FULL/DR         00:00:33    192.168.33.18   FastEthernet1/0/2 (NYWAN1 or NYCORE2)

I do not get DROTHER or 2WAY

I would clear the ospf process and see if it just got stuck in 2way.

@Ronnie-Wong i was thinking since

1. nycore 2 is directly connected to nycore 1
2. and both have vlan1
   they should form a neighborship on vlan1

is that wrong?

or maybe vlan1 subnet is not configured with the network command in the ospf configuration in NYCORE2

i figured it out

i thought since vlan 1 is configured on nycore2, i thought it will establish neighborship with nycore1. which i just checked, nycore2 is not running ospf to begin with. thanks

@BlueTeam3r,

Glad you figured it out, great job!
