What is the 'show route' command you are using to get this information? AFAIK, 'show route receive-protocol bgp' shows what is received, communities and all, prior to policy processing. In order to see the routes that have passed through your policy, just do 'show route 91.202.39.0/24 detail' and those communities should not show up. -evt _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
