我有一個Cisco ISR4431路由器，相關設定如下
ip access-list standard toGCP
10 permit 10.136.0.0 0.0.127.255
20 permit 10.136.128.0 0.0.127.255
30 permit 128.231.0.0 0.0.31.255
40 permit 128.231.32.0 0.0.31.255

還有show輸出

*> 128.231.32.0/19 0.0.0.0 32768 i

我的問題是我不要通告10.136.0.0/16，我只要通告4筆路由給BGP對等
128.231.32.0 / 19
128.231.0.0 / 19
10.136.128.0 / 17
10.136.0.0 / 17
請問我應該如何解決這個問題? 期望回覆與感激!
