Hello Ryan,
Please find the below snippet. If i missed something very obvious, please point
me out
Topology is r1-------r2
r1#show run int tunn0
Building configuration...
Current configuration : 145 bytes
!
interface Tunnel0
no ip address
ipv6 address 2001:1::1/64
ipv6 rip cisco12 enable
tunnel source 12.0.0.1
tunnel destination 12.0.0.2
end
r1#show run int lo0
Building configuration...
Current configuration : 90 bytes
!
interface Loopback0
no ip address
ipv6 address 1::1/128
ipv6 rip cisco12 enable
end
r1#ping 2001:1::2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:1::2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/24/48 ms
r1#show ipv6 route 2001:1::2
IPv6 Routing Table - 4 entries
Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP

I can also exchange to and fro from the other end.

Am I missing something ?

You'll be able to ping the IPv4 address but not the IPv6 without the tunnel
mode ipv6ip command. Give it a try. Configure the tunnel but don't put tunnel
mode ipv6ip and see if you can ping the ipv6 address on the other side of the
tunnel. It will fail. The IPv6 route will show as directly connected but
since the tunnel doesn't know to encapsulate the IPv6 traffic over IPv4 to send
across the tunnel (tunnel mode ipv6ip), your ping will fail. Once you put that
in there, you should be able to ping. If you then add your rip commands and
debug ipv6 rip, you'll see your rip updates coming across the tunnel.

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 ?

I believe you are talking about 32.9 in WB1. 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.

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 ?
