4.13. TD-SCDMA CE典型拓扑

典型拓扑结构采用“口字”结构如下图。一般配置有两台Juniper MX960作为CE路

由器，多台RNC设备通过MX960接入IP承载网。

图：RNC设备共址接入拓扑图

PS域组网说明：

每套RNC Iu-PS通过4块单板输出4路GE口与两个CE设备连接，其中1,2单板为主

用，连接CE1；第3，4板连接CE2, 第3板备份第1板，第4板备份第2板。

178

RNC两个主用单板上的2个端口分别配置位于不同网段的IP地址，并且将网关指向CE

上不同VLAN的下一跳，CE上的两个VLAN接口为RNC的下一跳并配置VRRP，CE1

相应VLAN接口为主用，CE2相应VLAN接口为备用。VRRP设置为跟踪上行接口，

这样当上行接口状态变化时也会触发VRRP切换。

CE上需要配置到达RNC的静态路由，发往RNC的报文总是会被直接送到该报文对应

用户面处理。

 CE设备之间通过GE Trunk互连，并在面向RNC侧的两个VLAN子网设置

VRRP倒换保护。

 每个RNC出4个光口分别与两个CE连接，两个主用接口之间通过等值多路

径(ECMP)路由配置实现端口间的IP负荷分担；

 另外两个备用接口为两个主用接口的备份

 多个RNC共用2个CE

 每个CE提供一个10GE端口通过IP承载网与SGSN连接

 CE之间通过GE Trunk互联，支持VRRP倒换保护

IP地址规划方案

179

RNC与CE互联网段

每个RNC都需要两个/29网段地址，RNC两个主用接口跟CE之间的两个互联网段都

使用一个/29的网段。其中RNC的两个主用接口个使用一个IP地址(不同网段)，两个

CE连接RNC的两个VLAN接口各使用一个IP地址，并由主用设备CE1接管不同于

VLAN接口IP的一个虚拟IP地址

CE与IP承载网AR互联网短段

需要两个 /30的子网，每个RNC跟各自的AR互联网段使用一个/30的网段

IP地址规划示例如下：

RNC GE1 :

CE1 VLAN1:

CE2 VLAN1:

192.168.0.1/29

192.168.0.2/29

192.168.0.3/29

192.168.0.6/29 VLAN1 VRRP:

RNC GE2 : 192.168.0.9/29

180

CE1 VLAN2:

CE2 VLAN2:

192.168.0.10/29

192.168.0.11/29

192.168.0.14/29 VLAN2 VRRP:

故障收敛说明

 RNC 第1单板到CE1的链路出现故障，由于此时CE1 VLAN1的所有端口并

没有全down(CE1和CE2之间的Trunk端口也包含VLAN1)，因此VLAN1

的VRRP不发生切换。此时RNC的端口主备发生切换，第3单板接替第1单

板工作，数据报文从第3单板发出，到达CE2，并通过CE1和CE2之间Trunk

端口到达CE1的VLAN1主用接口，再通过CE1到AR1的上联链路去往SGSN,

回来的数据报文跟据AR的配置可能从AR1->CE1返回，也可能从AR2->CE2

返回，两个路径都没有问题。

 RNC 第2单板到CE1的链路出现故障，由于CE1 VLAN2的所有端口并没有

全down(CE1和CE2之间的Trunk端口也包含VLAN2)，因此VLAN2 的

VRRP不发生切换。此时RNC的端口主备发生切换，第4单板接替第2单板

工作，数据报文从第4单板发出，到达CE2，并通过CE1和CE2之间Trunk

端口到达CE1的VLAN2主用接口，再通过CE1到AR1的上联链路去往SGSN,

回来的数据报文跟据AR的配置可能从AR1->CE1返回，也可能从AR2->CE2

返回，两个路径都没有问题。

 RNC的第3或第4单板到CE2的链路出现故障，因为这两条链路正常情况下

不承载业务，因此不触发切换，对业务无影响。

 CE1掉电，这时触发VRRP切换，两个VLAN地址的主用被CE2接管，RNC

181

的单板也发生切换，单板3，4为主用，此时业务不受影响

 CE1的上行链路出现故障，由于VRRP设置为跟踪上行接口状态变化，因此这

也会触发VRRP切换，CE2成为主用，RNC的第1单板和第2单板发出数据

报文，到达CE1，再通过CE1和CE2之间的Trunk链路将报文转发给CE2的

VLAN接口，然后通过CE2的上行链路往SGSN,回来的数据报文跟据AR的

配置可能从AR1->CE1返回，也可能从AR2->CE2返回，两个路径都没有问

题。

 CE2的上行链路出现故障，由于CE2正常情况下不承载业务，因此不触发切

换，对业务无影响。

4.13. TD-SCDMA CE典型拓扑

典型拓扑结构采用“口字”结构如下图。一般配置有两台Juniper MX960作为CE路

由器，多台RNC设备通过MX960接入IP承载网。

图：RNC设备共址接入拓扑图

PS域组网说明：

每套RNC Iu-PS通过4块单板输出4路GE口与两个CE设备连接，其中1,2单板为主

用，连接CE1；第3，4板连接CE2, 第3板备份第1板，第4板备份第2板。

178

RNC两个主用单板上的2个端口分别配置位于不同网段的IP地址，并且将网关指向CE

上不同VLAN的下一跳，CE上的两个VLAN接口为RNC的下一跳并配置VRRP，CE1

相应VLAN接口为主用，CE2相应VLAN接口为备用。VRRP设置为跟踪上行接口，

这样当上行接口状态变化时也会触发VRRP切换。

CE上需要配置到达RNC的静态路由，发往RNC的报文总是会被直接送到该报文对应

用户面处理。

 CE设备之间通过GE Trunk互连，并在面向RNC侧的两个VLAN子网设置

VRRP倒换保护。

 每个RNC出4个光口分别与两个CE连接，两个主用接口之间通过等值多路

径(ECMP)路由配置实现端口间的IP负荷分担；

 另外两个备用接口为两个主用接口的备份

 多个RNC共用2个CE

 每个CE提供一个10GE端口通过IP承载网与SGSN连接

 CE之间通过GE Trunk互联，支持VRRP倒换保护

IP地址规划方案

179

RNC与CE互联网段

每个RNC都需要两个/29网段地址，RNC两个主用接口跟CE之间的两个互联网段都

使用一个/29的网段。其中RNC的两个主用接口个使用一个IP地址(不同网段)，两个

CE连接RNC的两个VLAN接口各使用一个IP地址，并由主用设备CE1接管不同于

VLAN接口IP的一个虚拟IP地址

CE与IP承载网AR互联网短段

需要两个 /30的子网，每个RNC跟各自的AR互联网段使用一个/30的网段

IP地址规划示例如下：

RNC GE1 :

CE1 VLAN1:

CE2 VLAN1:

192.168.0.1/29

192.168.0.2/29

192.168.0.3/29

192.168.0.6/29 VLAN1 VRRP:

RNC GE2 : 192.168.0.9/29

180

CE1 VLAN2:

CE2 VLAN2:

192.168.0.10/29

192.168.0.11/29

192.168.0.14/29 VLAN2 VRRP:

故障收敛说明

 RNC 第1单板到CE1的链路出现故障，由于此时CE1 VLAN1的所有端口并

没有全down(CE1和CE2之间的Trunk端口也包含VLAN1)，因此VLAN1

的VRRP不发生切换。此时RNC的端口主备发生切换，第3单板接替第1单

板工作，数据报文从第3单板发出，到达CE2，并通过CE1和CE2之间Trunk

端口到达CE1的VLAN1主用接口，再通过CE1到AR1的上联链路去往SGSN,

回来的数据报文跟据AR的配置可能从AR1->CE1返回，也可能从AR2->CE2

返回，两个路径都没有问题。

 RNC 第2单板到CE1的链路出现故障，由于CE1 VLAN2的所有端口并没有

全down(CE1和CE2之间的Trunk端口也包含VLAN2)，因此VLAN2 的

VRRP不发生切换。此时RNC的端口主备发生切换，第4单板接替第2单板

工作，数据报文从第4单板发出，到达CE2，并通过CE1和CE2之间Trunk

端口到达CE1的VLAN2主用接口，再通过CE1到AR1的上联链路去往SGSN,

回来的数据报文跟据AR的配置可能从AR1->CE1返回，也可能从AR2->CE2

返回，两个路径都没有问题。

 RNC的第3或第4单板到CE2的链路出现故障，因为这两条链路正常情况下

不承载业务，因此不触发切换，对业务无影响。

 CE1掉电，这时触发VRRP切换，两个VLAN地址的主用被CE2接管，RNC

181

的单板也发生切换，单板3，4为主用，此时业务不受影响

 CE1的上行链路出现故障，由于VRRP设置为跟踪上行接口状态变化，因此这

也会触发VRRP切换，CE2成为主用，RNC的第1单板和第2单板发出数据

报文，到达CE1，再通过CE1和CE2之间的Trunk链路将报文转发给CE2的

VLAN接口，然后通过CE2的上行链路往SGSN,回来的数据报文跟据AR的

配置可能从AR1->CE1返回，也可能从AR2->CE2返回，两个路径都没有问

题。

 CE2的上行链路出现故障，由于CE2正常情况下不承载业务，因此不触发切

换，对业务无影响。
