[c-nsp] 6rd on ASR1k

[Ruslan Pustovoitov]

Hi all

I try to setup 6rd on asr1k accordingly to 
http://docwiki.cisco.com/wiki/6rd_Configuration_Example
Then I ping6 IPv6 host from client and see that IPv6 packet envelops in 
IPv4 with right IPv4 destination (6rd relay IPv4 address).
This IPv4 packet seccessfully reach asr1k and nothing else. Packets 
silently disappear.

The output of  "show tunnel 6rd tunnel 0Interface Tunnel0" dont show any 
counters info:
  Tunnel Source: 192.88.99.127
  6RD: Operational, V6 Prefix: 2YYY:ZZZZ:206::/48
       V4 Prefix, Length: 16, Value: 192.88.0.0
       V4 Suffix, Length: 0, Value: 0.0.0.0
  General Prefix: 2YYY:ZZZZ:206:637F::/64


Also, I don't see any IPv6 packet going from asr1k to IPv6 directly 
connected host where I run tcpdump.
