BGP community filtering IOS-XE

Hi,

I allow my customers to send some BGP communities, lets say 10:1 20:1 and 30:1. They can send none, some or all communities. I want to create a route map that checks on the sent communities and removes communities that are not in the allowed list but still propagates the other ones. Is there a way in IOS-XE to do this in a generic way (i.e. community lists with regex) or do I have to check on each community in one separate route map statement?

Thanks for any hint.

Mat

i think the most easy way is match and delete the communities one by one. If you use a regex expression could be insane matching all the possibilities but if you have free time go ahead :)
