Show ip ospf interface brief on packet tracer.

[Fabián Perilla]

Hello everyone!

I am using a topology from Wendell Odom's book:

my question is that I am using that topology to simulate the network on packet tracer, but when I issue the command

SHOW IP OSPF INTERFACE BRIEF

to see the neighbor count, it displays 0/0, already knowing that the neighbor adjacency was successfully completed: 

Above the picture showing 0/0

As you see the neighbor count is completed according to SPF logic if I issue the command

show ip ospf interface x

per interface. But I also have the

last version of PT 8.2.0

I really appreciate if you could give me a hand to solve this problem or understanding why packet tracer doesn't show it. Thanks in advance!

Answer is quite simple, PT is a simulator teaching tool, it's not an 100% full emulator or real device.

I.e. many "real" IOS features are not implemented or only implemented partially.

Not really understand the issue.

Do you like t see the neighbors, you need to use

show ip ospf neigh

The following command "show ip ospf int Gig0/0" shows the neighbor count as well as the adjacent neighbor count "Neighbor Count is 3, Adjacent neighbor count is 2".

R1-end>show ip ospf int Gig0/0

GigabitEthernet0/0 is up, line protocol is up

Internet address is 10.1.1.1/24, Area 0

Process ID 1, Router ID 1.1.1.1, Network Type BROADCAST, Cost: 1

Transmit Delay is 1 sec, State DROTHER, Priority 1

Designated Router (ID) 4.4.4.4, Interface address 10.1.1.4

Backup Designated Router (ID) 3.3.3.3, Interface address 10.1.1.3

Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5

Hello due in 00:00:06

Index 1/1, flood queue length 0

Next 0x0(0)/0x0(0)

Last flood scan length is 1, maximum is 1

Last flood scan time is 0 msec, maximum is 0 msec

Neighbor Count is 3, Adjacent neighbor count is 2

Adjacent with neighbor 4.4.4.4 (Designated Router)

Adjacent with neighbor 3.3.3.3 (Backup Designated Router)

Suppress hello for 0 neighbor(s)
