我正在尝试设置正常关闭社区，但看起来我无法使其正常工作。

community-set comm-graceful-shutdown
  65535:0
end-set
!
route-policy SOMEIX-IN
  ! tried set local-preference 0 here to test, useless because it is rewritten
  set community (65535:0) additive
  if community matches-any comm-graceful-shutdown then
    set local-preference 0
  else
    set local-preference 95
  endif
  ! if I put set local-preference 0 here, I can achieve to have localpref 0
end-policy

最后我得到了：

  Origin IGP, metric 0, localpref 95, valid, external, best, group-best
  Received Path ID 0, Local Path ID 0, version 416851127
  Community: <some communities, then:> graceful-shutdown

有人对我错了哪一点有想法吗？
