Marko,

I have one question please forgive me if I seem like a novice. I read up on
the technology which I believe is 6PE, second I followed your setup scenario
posted on your blog. However I was not allowed to ping from IPv6 CE to CE of
course it worked from PE to CE. In reading the Cisco docs one caveat was
IPv6 ICMP control message will not be passed at the edge. Is this the case
or have I missed something? One thing I failed to mentioned was I set this
up over Frame just to see what would happen.
