For the above Task can we use the local local prefrence at R6 ??
You are asked to configure AS200 to manipulate inbound traffic to AS200; local-preference would work for outbound traffic.
Optional solution would be to use as-prepend, but I am not 100% sure if it is allowed/prohibited in this lab.
mmmm got your point, local prefrence will work but as you said we need to configure AS200 and not As100
