if you are trying to set med values for the specifed network to 100 the route-map should be applied to the neighbor and not the network command as your route-map has the prefix list which defines the networks.
i presume you have already advertised the 172.20.255.0/26 into BGP from this router.
I aint trying to set any med values....I just set a med tag to see how the routes look in RT....
I am trying to see if we can use the network statement to group multiple prefixes under one network config statement, rather than 3 or 4 statements each pointing to 1specfic prefix... using prefix-list & route-map.
I tried with 1 prefix-list & 3 prefix-list to match the loopback ints...still I can only see 1 prefix being advertised(fist),,,not all of them.
Try this. Create a static route to your summary pointed to null0. Then advertise that in BGP and your policy should work. You have to have a specific route for BGP to advertise, and if you don't have a route pointing to your summary then you won't see the advertisement.
You'll need to change your prefix list to support just the summary and it should work. If you're wanting to change all routes that are advertised to the neighbor, you'll need to apply the route map to the neighbor and then you'll hit all entries in the prefix list.
** Edit **
I had some time to play around with this, and it doesn't look like you're going to be able to do what you're wanting to do. What the route-map on the network statement seems to do is to set whatever attribute you want on that route locally. In other words, you can set local pref, weight, etc, by putting a route-map on the network that you want to advertise. Weight, for example, is locally significant so you can set the route to be less preferred from your perspective. When you do your advertisement for your supernet, look at the bgp table that's on the router you're doing your advertisement on and you'll notice that you're also setting the metric on the local router which indicates to me that this is a "set and advertise" type of route-map. There are certain values that you cannot set like a tag and as-path prepending; you'll need to do that with the neighbor route-map. Another interesting thing that I noticed was that the route-map applied directly to the neighbor overrides the route-map applied to the network command.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
