OSPF Routing Protocol Not working

[ZAINALATTAS9656]

Hi Everyone, 

I am trying to ping from PC10 to PC-class1-internet but i am unable to do so . 

I have configured OSPF protocol on both the routers (R1 & R2) and all on the interfaces but still cant. 

THe network topology is attached for your information. 

Please need your help ASAP.

Hello ZAINALATTAS9656,

Your PCs connected to switches "Class_tutors" and "Switch_Class2" don't even have IPv6 assigned, only the Link Local Addresses. I'm not an expert in IPv6 but I'm pretty sure you need to use Unicast Addressing on all your PCs just as you did on PCs connected to switch "Center_Admins".

That's probably why you don't have any communication between those two rooms.

I hope this has been helpful.

Hi @ZAINALATTAS9656 ,

You have to make some changes to your settings:

Your serial links have the same network, so you must assign a different network to the link between Router1 and Router2.

You have some configurations that do not correspond in the link between the routers.

In short, your interfaces should look like this:

Router1

interface Serial0/3/1

bandwidth 64

no ip address

ipv6 address FE80::1 link-local

ipv6 address 2001:AD3:ABCD:8::1/64

ipv6 ospf 1 area 0

clock rate 64000

!

Router2

interface Serial0/3/0

bandwidth 64

no ip address

ipv6 address FE80::1 link-local

ipv6 address 2001:AD3:ABCD:8::2/64

ipv6 ospf 1 area 0

After those changes, the ping is successful:

I attached the file with the changes
