必要條件

採用元件

本文中的資訊係根據以下軟體和硬體版本：

Cisco IOS®軟體版本12.0(3)T或更高版本。

注意：要藉助分配了回撥字串的AAA伺服器配置PPP回撥，您需要使用dialer aaa命令，該命令在Cisco IOS軟體版本12.0(3)T或更高版本中可用。但是在Cisco IOS版本12.1(4)T、12.2(1)T和更新版本中，使用分配了回撥字串的AAA伺服器的PPP回撥不需要此命令。

註：只有傳統DDR支援dialer aaa 命令(如圖1所示)。

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路正在作用，請確保您已瞭解任何指令可能造成的影響。

背景資訊

TACACS+（AAA伺服器）用於向回撥伺服器提供回撥撥號字串。但是，也可以使用RADIUS提供回撥字串。要使用本地身份驗證、授權和記帳(AAA)配置PPP回撥，請參閱通過ISDN配置PPP回撥。

在此示例配置中，回撥使用PPP和RFC 1570中指定的工具。跨ISDN電路的PPP回撥按以下順序完成：

回叫客戶端發起並啟動到回叫伺服器路由器的ISDN連線。
回叫客戶端和回叫伺服器協商PPP鏈路控制協定(LCP)。在LCP協商中，回叫是請求、協商和商定的。
回叫客戶端和回叫伺服器使用PPP密碼身份驗證協定(PAP)或質詢握手身份驗證協定(CHAP)相互進行身份驗證。但是，可以通過ppp authentication chap callin 命令將回叫客戶端配置為不對回叫伺服器進行身份驗證。
回叫伺服器從AAA伺服器獲取必要的回叫屬性，如回叫撥號字串（客戶端的電話號碼）。
兩台路由器都斷開ISDN連線。
回叫伺服器向客戶端發起回叫。當呼叫連線時，路由器會相互進行身份驗證，然後建立鏈路。

設定

本節提供用於設定本文件中所述功能的資訊。

注意：要查詢有關本文檔中使用的命令的其他資訊，請使用命令查詢工具(僅限註冊客戶)。

組態

本檔案會使用以下設定：

免費軟體TACACS+配置
RADIUS組態
備用RADIUS配置
Tnt-buster（回撥伺服器）配置
Tremens（回撥客戶端）配置

免費軟體TACACS+配置
user = tremens { default service = permit login = cleartext "cisco" chap = cleartext "cisco" !--- CHAP password. service = ppp protocol = lcp { callback-dialstring = "6083" !--- Number to callback. send-secret = "cisco" } }

免費軟體TACACS+配置

user = tremens {
  default service = permit
  login = cleartext "cisco"
  chap = cleartext "cisco"
  
!--- CHAP password.

  service = ppp protocol = lcp {
  callback-dialstring = "6083"

 !--- Number to callback.

  send-secret = "cisco"
  }
  }

您還可以使用RADIUS作為AAA伺服器來提供回撥屬性，而不是TACACS+。以下提供RADIUS設定範例：

RADIUS組態
tremens Auth-Type = Local, Password = "cisco" Service-Type = Framed-User, !--- Service-Type(6) is Framed User(4). Cisco-AVPair = "lcp:callback-dialstring=6083", Cisco-AVPair = "lcp:send-secret=cisco"

RADIUS組態

tremens         Auth-Type = Local, Password = "cisco"
                Service-Type = Framed-User,

 !--- Service-Type(6) is Framed User(4).

                Cisco-AVPair = "lcp:callback-dialstring=6083", 
                Cisco-AVPair = "lcp:send-secret=cisco"

注意：在上述所示的RADIUS配置中，回叫的身份驗證時需要Cisco AVPair lcp:send-secret=cisco。如果不包括此AVPair，則必須在回撥伺服器上本地配置遠端路由器的CHAP使用者名稱和密碼。

注意：本檔案主要說明TACACS+。本文檔中提供的調試不顯示RADIUS啟動的回撥。

注意：從Cisco IOS版本12.1(7)開始，可以使用Internet工程任務組(IETF)RADIUS屬性19進行ISDN和模擬Microsoft回撥。在這種情況下，不需要使用如先前配置所示的Cisco AVPairs。請參閱此處顯示的備用RADIUS組態範例：

備用RADIUS配置
tremens Auth-Type = Local, Password = "cisco" Service-Type = callback framed !--- Service-Type (6) is callback framed (4). !--- Callback framed is also known as !--- Dialback-Framed-User. Callback =6083 !--- IETF RADIUS Callback attribute (19) with the phone !--- number for the callback.

備用RADIUS配置

tremens         Auth-Type = Local, Password = "cisco"
                Service-Type = callback framed
                
!--- Service-Type (6) is callback framed (4).

                
!--- Callback framed is also known as !--- Dialback-Framed-User.

                Callback =6083
                
!--- IETF RADIUS Callback attribute (19) with the phone !--- number for the callback.

注意：RADIUS調試將顯示返回到回撥伺服器的IETF RADIUS屬性19。
