How to Configure OSPF for VLAN Route | CISCO Packet Tracer | Video # 38

[@mnm121314]

Wow! This video is amazing! I had a hard time understanding OSPF and was wondering how to advertise those VLAN's. You answered everything in 1 clear video. Thank you!

Thank you soo much for your explanations. You helped me finish a project I spent a lot of time on, not knowing how to route those vlans

Or Sir, instead of enabling ospf for each vlans, we can simply redistribute directly connected routes to OSPF in HO_SW1.

[@networkforyou11]

Hi Yes you can do that also. Thanks

[@KLNYC]

what do you mean by that?

[@KLNYC]

Hi there, i copied it exactly like you have here.. It seem I cannot ping the 192,168.2.2 on the branch sw. I can ping other PC..

Hi, Better what app us. Our team will check and update you. Thanks

Step 1: Set up the network topology Add two switches and a router to your topology. Add VLANs to the switches: Configure each switch to have multiple VLANs. Assign hosts to VLANs on the switches. Trunk links between switches and router: Create a trunk port between the switch and the router for inter-VLAN routing. Step 2: Configure VLANs on the Switches Create VLANs on the switch: bash Switch> enable Switch# configure terminal Switch(config)# vlan 10 Switch(config-vlan)# name Sales Switch(config-vlan)# vlan 20 Switch(config-vlan)# name Engineering Switch(config-vlan)# exit Assign VLANs to interfaces: bash Switch(config)# interface fa0/1 Switch(config-if)# switchport mode access Switch(config-if)# switchport access vlan 10 Switch(config-if)# exit Switch(config)# interface fa0/2 Switch(config-if)# switchport mode access Switch(config-if)# switchport access vlan 20 Configure the trunk link between the switch and router: bash Switch(config)# interface fa0/24 Switch(config-if)# switchport mode trunk Step 3: Configure Inter-VLAN Routing on the Router Create sub-interfaces for each VLAN: bash Router> enable Router# configure terminal Router(config)# interface gig0/0.10 Router(config-subif)# encapsulation dot1Q 10 Router(config-subif)# ip address 192.168.10.1 255.255.255.0 Router(config-subif)# exit Router(config)# interface gig0/0.20 Router(config-subif)# encapsulation dot1Q 20 Router(config-subif)# ip address 192.168.20.1 255.255.255.0 Router(config-subif)# exit Configure OSPF on the router: bash Router(config)# router ospf 1 Router(config-router)# network 192.168.10.0 0.0.0.255 area 0 Router(config-router)# network 192.168.20.0 0.0.0.255 area 0 Step 4: Verify OSPF Configuration Check OSPF neighbor adjacency: bash Router# show ip ospf neighbor Verify OSPF routes: bash Router# show ip route ospf Step 5: Test Connectivity Test pinging between hosts in different VLANs to ensure the OSPF configuration is working. Ping from a host in VLAN 10 (e.g., 192.168.10.2) to a host in VLAN 20 (e.g., 192.168.20.2).

I added my L3 switch to the OSPF but neighbor router is not seeing it

Hi, What app us our team will check and update you. Thanks

[@somanathsshenoy]

Can i get your contact details? I have no words. Your are simply awesome. Need to talk to you.

[@networkforyou11]

Hi, What app us. Thanks

[@networkforyou11]

Thanks. Mustafa is my name

[@Yamukoo]

Sir why we needed router for vlan ?? 🙄

[@networkforyou11]

Hi, No need for router for Vlan. We configure Vlan fon switches. What is your question. We didn't get your questions. Thanks

[@networkforyou11]

Here we are saying we are sending routes not router. We are configuring ospf for that Vlan to send that Vlan routes Thanks

[@Yamukoo]

I saw u configure ospf for vlans . Actually why we have to do that ? 🙄

[@mnm121314]

@@Yamukoo They did it to advertise those VLAN's to the Backup Office on the other side. In a small Network, you don't need to do that if your company don't have a separate building, office, etc. In many enterprises, you do need to do what he showed in this video
