Choon Ho Loi,
For best feedback result, please check the online SHOWiT output and the online
Answer key. Also, post the online Forum and you can get answers from our
experts in this lab, and from others who have tackled this lab.
It looks to me like you have used prefix FEC0:: where we are using FEC1. But
that should not be a problem if you are consistent.
See you in the Netmasterclass Forum!

Subject: NMC lab scenario 8: Ipv6ip tunneling problem
Hi,
I had problem in attempting NMC lab 8 (ipv6 session)
Following is my configuration for R1 and R2.
I couldn't make ospf to work. I wonder what did I did wrong...
TIA.
R1:
interface Tunnel100
no ip address
no ip redirects
ipv6 address FEC0::/64 eui-64
ipv6 enable
no ipv6 nd suppress-ra
ipv6 ospf network non-broadcast
ipv6 ospf neighbor FEC0::5EFE:AC10:6601
ipv6 ospf 100 area 0
tunnel source Loopback0
tunnel mode ipv6ip isatap
Debug:
r1#sh ipv6 ospf nei
