Yes you can do this...here are some configuration examples from two routers that are shown below how you have described.<div><br><div><div>*A:r33>config>router# info </div><div>----------------------------------------------</div>

<br>
I am trying to get an IPv6 over IPv4 tunnel working on 2 7750s with<br>
7.0. Here is my plan:<br>
<br>
IPv6---R2<---IPv4--->R3---IPv6<br>
<br>
R2 and R3 will have a direct IPv4 connectivity.<br>
Each router will have a loopback as an endpoint for the tunnel (this<br>
will have IPv4 and IPv6 addresses).<br>
Then another loopback will have only IPv6 addressing to simulate an IPv6 LAN.<br>
Routing between the "LANs" will be done using static routes.<br>
<br>
Is this possible? I have been reading and following the 7.0 Router<br>
Guide pages 52-60. Not really sure what the guide is going for since<br>
no explanation or context is given for their configuration examples. I<br>
have no clue what BGP is doing there.<br>
<br>
Thanks,<br>
