| Answers Explanation & Hints:
Private BGP communities follow a convention where the first 16 bits represent the AS of the community organization, and the second 16 bits represent a pattern defined by the originating AS. A private BGP community pattern can vary from organization to organization, does not need to be registered, and can signify geographic locations for one AS while signifying a method of route advertisement in another AS. A private BGP community is set in a route map with the command set community bgpcommunity [ additive ]. |
