That sounds right to me. I was looking over using a route map to set local
preference in bgp and it looks like the last statement is necessary. In
fact, I just read about setting communinity filtering and the second
statement is required.
You may refer to pages 340-342 in the internet routing architectures by sam
halabi for further information.
HTH!

Hello,
I see that your configuration right but there is still left something. I
think you should add one route-map command to handle the others route to
pass with no change. You add like below:
route-map commun-out permit 20
Why we must this command?, because when we using route-map for policy
routing, the route that do not match the route-map statement will be
discarded.
I hope that help, correct me if i am wrong!
