Mike,
It looks like your route-map is configured to match an IP access-list called MEDOUT but you have a prefix-list configured. Try configuring your route-map like this and see if it helps:
route-map MEDOUT permit 10
match ip address prefix-list MED200
set metric 100
!
route-map MEDOUT permit 20
!

Hello,
In this task you are supposed to ensure that AS 100 traverse The peering between SW2 and R5 for prefix 150.1.11.0/24. To do this you need to use a route map on SW2 and R2 and set MED for this prefix to prefer The peering between SW2 and R5. When I tried doing this config it is setting the MED for all prefixes orginating in AS 100 not just the 150.1.11.0/24. Can someone please help me understand why this is doing this and what I need to change to get this to work.
Thanks in advance,
Mike F.
