However, I fail to see why (if) > you would like to allow the same route to source from muliple AS:es.... Why not? Suppose company A has a PA allocation 10.21.0.0/20. Company A gets a T1 from Carrier B. Carrier B announces 10.21.0.0/20 with their AS65531 and statically route the /20 to company A. If Company A wants to be redundant and gets another T1 from Carrier C, Carrier C will announce 10.21.0.0/20 with their AS65532 and statically route 10.21.0.0/20 to Company A. I see no problem in this. If Carrier B screws up, the traffic will still flow through Carrier C. If Carrier B screws up in such a way that they still announce the netspace, Carrier C can announce 2 /21's instead of 1 /20 so it will still work. -- Sabri Berisha "I route, therefore you are" ~ my own opinions etc ~ Join Megabit LAN in open air! http://www.megabit.nl
