no arp frame-relay,no frame-relay inverse-arp 这两条命令有什么差别,希望能讲清楚点

no frame-relay inverse arp says that I shall not ask the other end what his IP address is.
no arp frame-relay means that if the other end asks me my IP address,I shall not answer him.
第一条的意思是说关闭逆向ARP,即不回去询问其他设备的IP信息,当然询问只能通过逆向ARP
第二条的意思是说不想别的设备告知我的IP信息
