Explanation

The BGP extended communities attribute format has three fields: type: administrator: assigned-number. type is the type of extended community and can be either the 16-bit numerical identifier of a specific BGP extended community or one of these types: origin-- Identifies where the route originated. domain-id-- Identifies the OSPF domain from which the route originated. target-- Identifies the destination to which the route is going. bandwidth-- Sets up the bandwidth extended community. Specifying link bandwidth allows you to distribute traffic unequally among different BGP paths. rt-import-- Identifies the route to install in the routing table. src -as-- Identifies the AS from which the route originated. You must specify an AS number, not an IP address. communities-and-extended-communities-for-use-in-routing-policy-match-conditions.html
