These tags can control the propagation of routes, adjust the localpref assigned to them, and even null route traffic. Announced Communities All routes announced to customers are tagged with the following information: 4436:TCRI T The type of relationship that the route was learned through. C The continent where the route was learned. R The region where the route was learned, if in the US. I Internal usage only. IRR Filtering All customers announcements are filtered against Internet Routing Registry (IRR) databases. BGP speaking customers will be expected to maintain current and correct IRR entries. All nLayer announcements will be recorded under the as-set AS-NLAYER.
