=head1 NAME

    RH_BadHdrExtLen - Bad Hdr Ext Len in Routing Header

=head1 TARGET

    Router

=head1 SYNOPSIS

=begin html
    <PRE>
    <A HREF="./RH_BadHdrExtLen.seq">RH_BadHdrExtLen.seq</A> [-tooloption ...] -pkt <A HREF="./RH_BadHdrExtLen.def">RH_BadHdrExtLen.def</A>
        -tooloption : v6eval tool option
    </PRE>

=end html

=head1 INITIALIZATION

    1. Check Link0 Global Address Reachability
    2. Check Link1 Global Address Reachability
    3. Check Global Address Reachability (from Link0 to Link1)
    4. Check support of Routing Header

=head1 TEST PROCEDURE

    1. Send bad Echo Request (Link0)
    2. Wait 5 sec.
    3. Send Echo Request (Link0)
    4. If NS received then send NA, and wait Echo Reply again (Link1)
    5. Receive Echo Request (Link1)

    Test Topology is:
