Marcus,
Isn't "no bgp synchronization" enabled by default now on routers with 12.2T. On 3550's, I believe it's still disabled.
Rack1R2(config)#router bgp 100
Rack1R2(config-router)#do sho run | b bgp
router bgp 100
no synchronization
bgp log-neighbor-changes
no auto-summary
Rack1SW2(config)#ip routing
Rack1SW2(config)#router bgp 100
Rack1SW2(config-router)#do sho run | b bgp
router bgp 100
bgp log-neighbor-changes
Rack1SW2(config-router)#no synchronization
Rack1SW2(config-router)#do sho run | b bgp
router bgp 100
no synchronization
bgp log-neighbor-changes
Jerry
