This is slightly prehistoric...

We're fairly happy with 15.1(2)SY4 and with 12.2(33)SXI14.  

Both support 4byte-ASNs and the usual 6500 stuff (Sup720-10G here).

Caveat: there's a couple of Cisco PSIRT advisories that both versions
*are* affected - so if you upgrade anyway, go for 15.1(2)SY7 or see
if the issues in SXI affect you.  There seems to be no SXI release that
has everything fixed, so you could give SXJ a try - but I have no personal
experience with recent SXJ versions (early ones were not very stable).
