Hi.
I attached the zipped Packet Tracer topology.
I can't ping from PC0 to Switch (SW2). It says it's unreachable. I configured the IP address 172.10.99.56 on interface Vlan 99 with ip default-gateway 172.10.99.1. The ip gateway is also configured on router interface using router on a stick(R1).
The vlan 99 is created. The interface Vlan99 is set with up status
What is missing in this case?

no file attached; it must be in a zip format; try again

Hi
I've attached the file. Can you see it now?

Yes, PT file shows that you are not allowing vlan 99 on trunks? why not ?

Vlan 99 it's a native vlan
I set on fa0/1 and fa0/3 ports from SW1 and SW 2 by switch trunk native vlan 99
On SW 2:
Switch#sh interfaces trunk
Port Mode Encapsulation Status Native vlan
Fa0/1 on 802.1q trunking 99
Fa0/3 on 802.1q trunking 99
Port Vlans allowed on trunk
Fa0/1 10,20,30
Fa0/3 10,20,30
Port Vlans allowed and active in management domain
Fa0/1 10,20,30
Fa0/3 10,20,30
Port Vlans in spanning tree forwarding state and not pruned
Fa0/1 10,20,30
Fa0/3 none

Hello,
I think it is a flaw in Packet Tracer. The only way I got it to work, that is, to make the Vlan 99 (and Vlan 1) interfaces on SW2 come up, is when using the configuration below on the trunk ports of both switches. It did not work even when allowing vlan 99.
interface FastEthernet0/1
switchport trunk native vlan 99
switchport mode trunk
!
interface FastEthernet0/3
switchport trunk native vlan 99
switchport mode trunk

I'm using Packet Tracer 7.3.0.
I set on fa0/1 and fa0/3 ports from SW1 and SW 2 by entering switch trunk native vlan 99. Also I tried the configuration shows like you've shown in previuos post but it didn't work. I could ping from PC 0 to SW1 but I couln't to SW2. The topology it's homework/exercise.

also do no shut on interface vlan 99. Confirm with show ip interface brief, you should see up up.
10-15-2020 05:18 PM
Ok
I'm giving you the output for vlan 99 using show ip interface brief on SW2
Interface IP-Address OK? Method Status Protocol
Vlan99 172.17.99.56 YES manual up down

I can't open the pkt file from vl 99 native.zip. I'm using packet tracer 7.3.0. What Packet Tracer version number are you using?

Oh, I updated to latest PT 7.3.1
just add vlan 99 to all trunks (or allow all). then after links come up, do no shut on interface vlan 99 on sw 2
