here is a nice write-up if someone wants to get more ideas on redundancy !
http://robert.penz.name/779/howto-setup-a-redundant-and-secure-bgp-full-table-internet-connection-with-mikrotik-routers/ As the network grows, needing to do maint. tends to be the # 1 reason for a complex redundant setup :) (irrespective of whose devices you are using... some of the larger Juniper's and Brocade's offer dual controllers which allows for the router to seamless flip between one side vs the other, that is something very neat... having seen that in our old Riverstone Routers...except for the price difference...)
