OSPF Multiple Areas Configuration

[violetta1405]

Hi, My name is Quan. I am new to OSPF and dynamic routing.
I've been learning about RIPv2 configurations and OSPF configurations.
While i am doing in this OSPF Multiple Areas lab 

I had a problem regarding the routing table doesn't show results as I thought. HUE router and CANTHO router doesn't have O*E2 (default route) even though I configured everything correct then I asked chat GPT to help me then it guided me to turn on Vlan1 for SAIGON and DANANG and it fixed the problem
Here is my configuration:

Hello,

Im not sure what turning on VLAN 1 did to fix anything. Glancing at your config it looks fine. 

Can you provide the output of the following commands on the routers:

show ip ospf neigh

sh ip route ospf

-David

[violetta1405]

Here is the result of all 6 routers:

[M02@rt37]

Hello @violetta1405 

On HAIPHONG router, do you succeed to ping IP 1.2.3.4 ?

Please show outputs that David ask for. Thanks a lot.

[violetta1405]

I successfully ping the ISP interface with the ip of 1.2.3.4

[Joseph W. Doherty]

Attach your PT file to OP.

[violetta1405]

How do I attach pkt file to the post? It doesn't allow me to attach it
Thank you.

[violetta1405]

I zipped the pkt file. I wonder if I didn't have O*E2 becauses I configure dhcp pool on router or I didn't fully configure before connecting these devices with cables

[Joseph W. Doherty]

I had a problem regarding the routing table doesn't show results as I thought. HUE router and CANTHO router doesn't have O*E2 (default route) . . .

When I bring up your recently attached PT file:

Seems to be present on both those routers, for me.

What version of PT are you running?

I'm running 8.2.2.0400.

[violetta1405]

I think i am running on 8.2.1

btw I closed it and checked and yeah it appears the O*E2 now
maybe the problem was I haven't fully configured before connecting these devices using cables so it contradicts ?

[Joseph W. Doherty]

Possibility, or maybe you didn't allow enough time for PT's OSPF to fully converge?  (I often use the time acceleration button to eliminate waiting for devices to boot, STP to converge, etc.)

BTW, you might find PT's version by using the menu's help about.

[violetta1405]

Hmn weirdly I took an amount of time checking for wrong configurations tho so might be time is not the problem but thanks for the tip
