I installed 15.1(1)XB in February on my Cisco 1801, which is one of the ones which has this bug fixed, however I could not route IPv6 over the bridged/BVI interface. I lost interest for a little while, earlier I installed 15.1(1)T, but v6 still does not work over the v6 interface.<br></span><div><font class="Apple-style-span" face="monospace"><br></font></div><div><font class="Apple-style-span" face="monospace">By 'work', I mean pass v6 frames, act as a gateway, do ND, do router advertisement.</font></div><div><font class="Apple-style-span" face="monospace"><br></font></div><div><font class="Apple-style-span" face="monospace">If the bug *is* fixed, then is it my config which is wrong, surely..
