After about a month of testing, we have several 6506's and 6506-E's with dual Sup720-3BXL's in SSO, running 12.2(3)SXI4a Advanced IP Services (monolithic) doing IS-IS, NSF, BGP, LDP, BFD, MPLS TE, and IPv6 among other things currently in production. We haven't run into any bad experiences thus far. It has fixed a couple of minor odd issues we had with much older trains. Two of the boxes have two complete copies of the v4 routing table via direct eBGP peers, and another has a total of about 100 BGP peers (mix of iBGP and eBGP IPv4 and IPv6). Do your own testing of course. :)
