IPCP协议里的NAK是什么？

hure

我PPPoE拨号抓包发现在IPCP阶段有下面6个包：<br /><br />(1) CPE给BAS<br />Code: Configuration Request (0x01)<br />Identifier: 0x05<br />IP address: 0.0.0.0<br />rimary DNS server IP address: 0.0.0.0<br />Secondary DNS server IP address: 0.0.0.0<br /><br />(2) BAS给CPE<br />Code: Configuration Request (0x01)<br />Identifier: 0xe3<br />IP address: 136.1.1.1<br /><br />(3) CPE给BAS<br />Code: Configuration Ack (0x02)<br />Identifier: 0xe3<br />IP address: 136.1.1.1<br /><br />(4) BAS给CPE<br />Code: Configuration Nak (0x03)<br />Identifier: 0x05<br />IP address: 136.1.1.3<br />rimary DNS server IP address: 10.63.172.68<br />Secondary DNS server IP address: 10.63.172.184<br /><br />(5) CPE给BAS<br />Code: Configuration Request (0x01)<br />Identifier: 0x06<br />IP address: 136.1.1.3<br />rimary DNS server IP address: 10.63.172.68<br />Secondary DNS server IP address: 10.63.172.184<br /><br />(6) BAS给CPE<br />Code: Configuration Ack (0x02)<br />Identifier: 0x06<br />IP address: 136.1.1.3<br />rimary DNS server IP address: 10.63.172.68<br />Secondary DNS server IP address: 10.63.172.184<br /><br />BAS的IP地址只用了2、3两个包，分配的IP地址和DNS怎么要4个包这么复杂呢？<br /><br />网上查了半天，没查到NAK是什么意思？
