Redirecting tail's stderr won't redirect the undesirable lines, if it's not the thing printing them in the first place. Lines going to standard error don't go through your pipe chain, they go direct from traceroute to the terminal. Redirect traceroute's stderr and they should go away.

Code:
traceroute ... 2>/dev/null | command1 | command2 ...

traceroute6

TRACEROUTE6(8)						 System Manager's Manual: iputils					    TRACEROUTE6(8)

NAME

       traceroute6 - traces path to a network host

SYNOPSIS

       traceroute6 [-dnrvV] [-i interface] [-m max_ttl] [-p port] [-q max_probes] [-s source] [-w wait time] destination [size]

DESCRIPTION

       Description can be found in traceroute(8), all the references to IP replaced to IPv6. It is needless to copy the description from there.

SEE ALSO

       traceroute(8), tracepath(8), ping(8).

HISTORY

       This program has long history. Author of traceroute is Van Jacobson and it first appeared in 1988. This clone is based on a port of tracer-
       oute to IPv6 published in NRL IPv6 distribution in 1996. In turn, it was ported to Linux by Pedro Roque. After this it was kept in sync	by
       Alexey Kuznetsov <kuznet@ms2.inr.ac.ru>. And eventually entered iputils package.

SECURITY

       tracepath6 requires CAP_NET_RAW capability to be executed. It is safe to be used as set-uid root.

AVAILABILITY

       traceroute6  is part of iputils package and the latest versions are  available in source form at http://www.skbuff.net/iputils/iputils-cur-
       rent.tar.bz2.
