My settings and my test in the attachments. Cannot ping the tunnel0 server(peer) ipv6 address. I'm using a Cisco ASR
FASTA-ASR#ping 2001:***:**:B2::1 source 2001:***:**:B2::2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:***:**:B2::1, timeout is 2 seconds:
Packet sent with a source address of 2001:***:**:B2::2
.....
Success rate is 0 percent (0/5)
What am I doing wrong?
Why'd you upload a screenshot of the IP addresses if you blacked them out?
Did you enable IPv6 routing on the router? I don't remember the exact command, but I remember seeing multiple posts on the forums that mention it.
Because I wasn't sure if that's allowed, anyways the ipv6 unicast-routing is configured.
Router#show run | inc ipv6 unicast-routing
ipv6 unicast-routing
Router#ping 2001:470:10:B2::1 source 2001:470:10:B2::2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:470:10:B2::1, timeout is 2 seconds:
Packet sent with a source address of 2001:470:10:B2::2
.....

I didn't think the routing statement would matter because you're not doing any sort of routing, but you never know.
Taking a stab...is your ISP blocking protocol 41?
How could I test that?
The easiest way is to ask them, although they will probably be confused
You could also do a packet capture, but that takes more work. Can you post your config with the addresses visible? If you don't want to, send it in a message instead

The ISP says it is not filtering any protocol
I have ping(ed) from HE looking glass and I get packets matched by a test access-list
FASTA-ASR#show access-lists 100
Extended IP access list 100
10 permit 41 any any log (252 matches)
I don't see anything glaring with your config, but I don't have enough experience building a tunnel on a Cisco router to say for sure. My only other suggestion is to check your MTU. Hopefully someone else sees what I missed.
Have tried using another Tunnel Broker and it works like a charm. However, I need BGP(6).
I've also sent an email to he.net but no one replied.
Can anybody help?
BGP tunnels are manually approved. They are not configured until approved.
Your ticket to request one was opened 44 hours ago by our system.
No replies from you to that ticket.

If not, your emails aren't making it to our system.
Sorry I don't understand the procedure: to ping the peer I should have approved the BGP tunnel?
is that why I cannot ping the peer?
I have received this confirmation on February 25th:

Thanks for answering,
HE needs to approve the BGP tunnel after a vetting process. Sorry your other ticket didn't get responded to yet.
