But It seems to happen, so in the Maintenance Window, it must be clear that
Services are going to be affected.
Yeah, bad experience with that also

Resuming the config to the parts that are not needed
interface Serial0/1
ip address 191.1.45.5 255.255.255.128
router ospf 1
router-id 150.1.5.5
area 45 virtual-link 150.1.4.4
network 191.1.45.5 0.0.0.0 area 45
interface Serial0/1
ip address 191.1.45.4 255.255.255.128
router ospf 1
router-id 150.1.4.4
area 45 virtual-link 150.1.5.5
network 191.1.45.4 0.0.0.0 area 45
I do not see any typos.
Also the no passive-interface Serial0/1 had been issued So there is no
problem at all with Hellos Did you try to clear the ip ospf process? Or
reload the routers?
Maybe you have a Router ID Problem, do a show ip ospf first to see what
router id they have

Hi there Russ,
AFAIK, in this LAB there was an authentication requirement.
Did you configure OSPF area 0 authentication on another router.
And Router4 config has an typo;
network 191.1.48.4 0.0.0.0 area 4 ----> sould be "area 48"
No Hellos (Passive interface) ----> indicating your problem
As I read many times on GS, do what they are asking, passive interface usage
is not a requirement in this scenario, but it can be useful in reallife.
Cheers,
Kemal

Subject: OSPF Virtual Link Issues ---
Hi All,
I am running into trouble with Virtual links in OSPF --- I keep getting the
following states with the Virtual link (below) ---
The router IDs are correct -- the link is a simple back to back ppp link
(with an OSPF adj over it) -- -however I keep getting the following:
On one side:
Virtual Link OSPF_VL2 to router 150.1.5.5 is up
Run as demand circuit
DoNotAge LSA allowed.
Transit area 45, via interface Serial0/1, Cost of using 64
Transmit Delay is 1 sec, State POINT_TO_POINT,
Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5
No Hellos (Passive interface)
Adjacency State INIT (Hello suppressed)
Index 0/0, retransmission queue length 0, number of retransmission 0
First 0x0(0)/0x0(0) Next 0x0(0)/0x0(0)
Last retransmission scan length is 0, maximum is 0
Last retransmission scan time is 0 msec, maximum is 0 msec
On the other:
Virtual Link OSPF_VL0 to router 150.1.4.4 is up
Run as demand circuit
DoNotAge LSA allowed.
Transit area 45, via interface Serial0/1, Cost of using 64
Transmit Delay is 1 sec, State POINT_TO_POINT,
Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5
Hello due in 00:00:02
I am stumped --- all looks fine --- but I'm sure I'm missing something...
HELP --- this should be soo simple....??...!!
Here are the relevant pieces of config too:
interface Serial0/1
ip address 191.1.45.5 255.255.255.128
router ospf 1
router-id 150.1.5.5
log-adjacency-changes
area 45 virtual-link 150.1.4.4
network 191.1.45.5 0.0.0.0 area 45
==============================
interface Serial0/1
ip address 191.1.45.4 255.255.255.128
router ospf 1
router-id 150.1.4.4

area 45 virtual-link 150.1.5.5
