Hello Ryan, Thank you for the reply. Will not be able to ping the other end with normal GRE encapsulation by default , without hardcoding IPv6ip ?

The tunnel mode ipv6ip specifies ipv6 as a passenger protocol to transport over the ipv4 network. I'm not sure how you were able to successfully ping, but since the task requires running rip across the tunnel, you should be able to debug ip rip and see updates coming from tunnel x. If you setup your tunnel and don't apply the rip configuration, you should be able to ping the ipv6 address across the tunnel. Here is a good link describing all the tunnels for ipv6. Marko has also written a few blogs on the subject. Just google ipv6 tunnel ipexpert to find them. http://www.cisco.com/en/US/docs/ios-xml/ios/interface/configuration/xe-3s/ip6-ipoverip6-tunls-xe.html#GUID-F963503B-27C8-49E9-A9AB-FE73298209FF On Fri, Dec 28, 2012 at 6:59 AM, Rock's M <[email protected]> wrote: Hello, If the below request is not in the proper channel / mailing list , please guide me, This is the first post into this mailing list. In Vol 1 lab32, the Tunnel mode was used to be ipv6ip , i did the lab initially without having a look at solution, but later found that we should use ipv6ip mode for tunnel interface between r2 and r5 ? Is there any specific requirement as i could ping across everything without using the mode ? Also, there was an acl to allow the tunnel ip's on R7,8,9 , which i did not require. Please advice about tunnel mode and acl ? _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
