( see <http://www.cisco.com/warp/public/770/index.shtml?60,8> for "Cisco IOS 12.2 and 12.2T Release Numbering Changes" Do you need IPv6 with "official" support ? why the "T" series ? If you really _must_ use 12.2T are you having problems with BGP next hop? then try checking bug _CSCdu74704_ - supposedly fixed in IOS 12.2(2)T02 --- A Cisco 7200 or 7500 series router that is running Cisco IOS Release 12.2(2)T may experience high CPU utilization for a "BGP Router" process if the router is configured for eBGP peering and the next hop becomes unreachable (for example, when an interface to an external peer is shut down). High CPU utilization occurs only if the router must send a large number of withdrawn routes to other peers because the next hop is unreachable. There is no workaround. - Rafi
