Can't ping from Host 1 to Host 2

[justindabear]

Hi all,

I'm working on a lab for school that requires me to configure IPv6 addresses as well as OSPFv3 process 20 on the four routers listed. My lab asks me to ping from Host 1 to Host 2 to ensure it is working properly but it's telling me that the Fa0/0 interface on Router 1 is not reachable. All my links are green. Default gateways are set properly. Any insight would be super helpful and could save my grade lol. 

Thanks!

1. configure the router IDs to start ospf process

2. make sure your IP address in Host 2 is correct

3. make sure IP addresses between routers are in correct networks 

4. check the routing table after OSPF neighbors joined
