OSPF Configuration On Layer3Switch | Networking Academy |

- Open Shortest Path First (OSPF) is a link-state routing protocol that is used to find the best path between the source and the destination router using its own Shortest Path First). OSPF is developed by Internet Engineering Task Force (IETF) as one of the Interior Gateway Protocol (IGP), i.e, the protocol which aims at moving the packet within a large autonomous system or routing domain. It is a network layer protocol which works on protocol number 89 and uses AD value 110. OSPF uses multicast address 224.0.0.5 for normal communication and 224.0.0.6 for update to designated router(DR)/Backup Designated Router (BDR).

If you successfully configured this video, Mention it in the comment section. Than you NA ❤
It worked like a charm . Thank you for providing this video. I even modified connectivity between the physical interfaces and made them a trunk
Glad it helped
Great Content
Thanks
Thanks for sharing info. Also plzz suggest if I want to block traffic with vlan wise in different ospf Areas.
Thank you for watching our videos. Use intervlan configuration and use Acl configuration to block vlans.
I did everything that you did in my lab using PT 8.2.0 and the packets stop at the router every time I go to ping .
Im using a 2900 router maybe its because program doesn't fully support ipv6 ospfv3 using that router in packet tracer. I've been trying to fix this 5 days in a row now and still can't get it.
The configuration is done on Layer2switch. Why don't you try it again. Please mail us the error message.
Hi, great video, so if we configure Layerb3 ether channel , can vlan still communicate?
And can we configure inter vlan on this setup and make routing between vlan to vlan ?
Thanks
Yes, of course
hello! great video, but i have a question, i use ur video as refrence, but i need to add more l3 switch in the middle, could the configuration be the same? what should i config in the l3 switch i just added? as a bridge between 2 l3 switch i mean
Yes just follow the same configuration on newly added l3 switch. All network address should be in ospf network list, then you can ping between other network.
If,
L3 switch 1 - 192.168.1.1 (Valn ip)
gig 0/1 - 1.1.1.1 (cable port of l3Switch 1)
gig 0/1 - 1.1.1.2 (cable port of l3Switch 2)
L3 switch 2 - 192.168.2.1 (Valn ip)
gig 0/1 - 2.2.2.1 (cable port of l3Switch 2)
gig 0/1 - 2.2.2.2 (cable port of l3Switch 3)
L3 switch 3 - 192.168.3.1 (Valn ip)

If this works mention it in the comment section with your feedback, it will help others too. THANK YOU
@@NetworkingAcademy1 okay but what if i cant add ip into l3 switch? its like its unassignable
Assign ip address for vlan and assign the ports to access vlan. Thats all my friend.
Sorry,May I ask you?How to configure if adding an L3 switch?
To make it more confirm, you were asking about adding a layer 3 switch for the network we configured on the video or any other network which you designed?
@@NetworkingAcademy1 Sorry, I use your video as a reference and ask questions on other platforms, please forgive me.
@Alvin chen, it okay. Just add the l3 switch and add the network for all other l3 switch to get connectivity with other networks.
@@NetworkingAcademy1 Yes, but the configuration where I added another L3 switch is failing, don't know what the problem is?
My configured directives:
SW3
Switch(config)#vlan 2
Switch(config)#vlan 3
Switch(config)#interface vlan 2
Switch(config-if)#ip address 192.168.3.1 255.255.255.0
Switch(config)#interface range fastEthernet 0/1-2
Switch(config-if-range)#switchport access vlan 2
Switch(config-if-range)#no shutdown
Switch(config)#interface vlan 3
Switch(config-if)#ip address 1.1.1.3 255.0.0.0
Switch(config-if)#no shutdown
Switch(config)#interface gigabitEthernet 0/2
Switch(config-if)#switchport access vlan 3
Switch(config-if)#no shutdown
SW3(OSPF)
Switch(config)#ip routing
Switch(config)#router ospf 10
Switch(config-router)#network 1.1.1.0 0.0.0.255 area 1
Switch(config-router)#network 192.168.3.0 0.0.0.255 area 1
Switch(config-router)#network 192.168.2.0 0.0.0.255 area 1
Switch(config-router)#exit
----------------------------------
SW2
Switch(config)#interface gigabitEthernet 0/2
Switch(config-if)#switchport access vlan 3
Switch(config-if)#no shutdown
SW2(OSPF)
Switch(config)#ip routing
Switch(config)#router ospf 10
Switch(config-router)#network 192.168.3.0 0.0.0.255 area 1
Switch(config-router)#exit
-----------------------------------
Can you help me with the correct settings? Please...My friends
This can be funny but just follow this some time it works.
Add every network.
for example.
if the networks address are. 1.1.1.0 , 192.168.1.0 , 192.168.2.0 , 192.168.3.0.
Switch(config)#ip routing
Switch(config)#router ospf 10
Switch(config-router)#network 1.1.1.0 0.0.0.255 area 1
Switch(config-router)#network 192.168.1.0 0.0.0.255 area 1
Switch(config-router)#network 192.168.3.0 0.0.0.255 area 1
Switch(config-router)#network 192.168.2.0 0.0.0.255 area 1
Switch(config-router)#exit
Every network should be in every switch or router devices you add, Try this my friend.
