This integer specifies a BGP Community value, per RFC 1997, used as a match condition for this import policy, and the source description excludes the reserved ranges 0 through 0x0000FFFF and 0xFFFF0000 through 0xFFFFFFFF from valid configuration. An admin sets it to import or filter routes based on a community tag applied by an upstream provider or another site, a common technique for signaling routing intent between autonomous systems. For example, setting csImpPolBgpCommunity1 to match a provider's 'customer-route' community value lets this policy single out routes carrying that tag.
