[6bone] Problems with big packets!?

[Alvaro Vives]

Hi all,

We've a host connected to 6BONE through a tunnel. The traceroute6 and ping6
to 3ffe:3328:6:2b01::a100 works fine, BUT if we try:

#ping6 -s 5000 3ffe:3328:6:2b01::a100

ALL the packets are lost! (-s specifies the size in bytes).

We tried ping6 (-s 5000 & -s 1000) to each node in the route, and in one of
them seems to be the problem:

2001:660:1102:4007::2

Somebody else have experienced this?

Regards,

Alvaro.

Se the pings and traceroute below:

# ping6 -s 1000 3ffe:3328:6:2b01::a100
