Connectivity issue for Paris peer
« on: June 28, 2011, 04:56:58 AM »

Hello,

I have a connectivity issue. The tunnel Server  <http://tunnelbroker.net/status.php>status page seems to be ok. Maybe Paris
peer is facing an issue. Could you help me for few minutes ?

traceroute to 2001:470:1F12:50F::2 (2001:470:1f12:50f::2), 30 hops
max, 40 byte packets

Here you have more details about the issue. The 6in4 tunnel interface is OK but IPv6 routing is not :

GSRTIP6#sh ipv6 interface brief
FastEthernet0/0            [up/up]
    FE80::F1
    2001:470:CAA8:80::1
FastEthernet0/1            [up/up]
Tunnel0                    [up/up]
    FE80::C232:2738

    2001:470:1F12:50F::2

I can ping the tunnel server:
GSRTIP6#ping 2001:470:1F12:50F::1
Success rate is 100 percent (5/5), round-trip min/avg/max = 16/24/32 ms

Same for 10gigabitethernet1-2.core1.par1.he.net
GSRTIP6#ping 2001:470:0:7b::2
Sending 5, 100-byte ICMP Echos to 2001:470:0:7B::2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/27/32 ms

I can ping the DNS:
GSRTIP6#ping 2001:470:20::2
Success rate is 100 percent (5/5), round-trip min/avg/max = 16/25/32 ms

I cant ping the core:
10gigabitethernet1-2.core1.par1.he.net (2001:470:0:48::1)
GSRTIP6#ping 2001:470:0:48::1
Sending 5, 100-byte ICMP Echos to 2001:470:0:48::1, timeout is 2 seconds:
Success rate is 0 percent (0/5)

From outside, I am joining your side of the tunnel but not mine :
PING 2001:470:1F12:50F::1(2001:470:1f12:50f::1) 56 data bytes
64 bytes from 2001:470:1f12:50f::1: icmp_seq=1 ttl=57 time=92.3 ms
64 bytes from 2001:470:1f12:50f::1: icmp_seq=2 ttl=57 time=23.2 ms

I can't ping google too from my router :
2a00:1450:4001:c01::93

GSRTIP6#ping 2a00:1450:4001:c01::93

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2A00:1450:4001:C01::93, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)

I did change anything in my config. I was working fine before.
