      i want to send a community a prefix but i cant do this because on route-map sending community to al prefixes

      is not useful because when i want blackhole a prefix i need to blackhole all prefixes and its very bad situation

          @derelict when i need send a community to my upstream for block announce of to a peer for 1 prefix i cant do

          how i can send to a community only 1 prefix ?
          when i need send a community
          community will send all prefixes.

          my prefix list like thİs
          prefix list xxxx-OUT
          sequence 1 permit x.x.x.0/24
          sequence 2 permit x.x.x.0/24
          sequence 3 permit x.x.x.0/24

          my route-map like this
          route dynamic route-map xxxx-OUT-RM
          sequence 10
          policy permit
          match ip address prefix-list xxxx-OUT
          set community "1111:2222"

            @sponner You would need to make a prefix list for the prefix you want to the community set on, match on that, set the community, then in a later sequence match the prefixes to be announced without setting the community, delete all communities from the routes, etc.

              @derelict yes but i want to send community to only one prefix but i cant do this because this route map sending community to all prefixes

                @sponner You are matching all prefixes in the prefix-list when you set the community. You are not stripping any existing communities on announced routes. Still not exactly sure what you are looking to do. What prefix do you want to tag with the community and what communities exist on the routes being announced?

                  I'm talking about something like this (untested):

                  prefix list xxxx-OUT
                  sequence 1 permit x.x.x.0/24
                  sequence 2 permit y.y.y.0/24
                  sequence 3 permit z.z.z.0/24

                  prefix list AddCommunity-OUT
                  sequence 1 permit z.z.z.0/24

                  my route-map like this
                  route dynamic route-map xxxx-OUT-RM
                  sequence 10
                  policy permit
                  match ip address prefix-list AddCommunity-OUT
                  set community "1111:2222"
                  sequence 20
                  policy permit
                  match ip address prefix-list xxxx-OUT
