如何确定Juniper路由器是否是路由反射器客户端？

Question

当我读到bgp路由器反射器文档时：

你看拓扑是这样的：

您可以看到路由器A、B、C在一个集群中，D不是它的客户端。但如何配置成这样呢？

我与路由器B和D比较：

set interfaces fe-0/0/0 unit 2 description to-A
set interfaces fe-0/0/0 unit 2 family inet address 10.10.10.2/30
set interfaces fe-0/0/1 unit 5 description to-C
set interfaces fe-0/0/1 unit 5 family inet address 10.10.10.5/30
set interfaces lo0 unit 2 family inet address 192.163.6.4/32
set protocols bgp group internal-peers type internal
set protocols bgp group internal-peers local-address 192.163.6.4
set protocols bgp group internal-peers export send-ospf
set protocols bgp group internal-peers neighbor 192.168.6.5
set protocols ospf area 0.0.0.0 interface lo0.2 passive
set protocols ospf area 0.0.0.0 interface fe-0/0/0.2
set protocols ospf area 0.0.0.0 interface fe-0/0/1.5
set policy-options policy-statement send-ospf term 2 from protocol ospf
set policy-options policy-statement send-ospf term 2 then accept
set routing-options router-id 192.163.6.4
set routing-options autonomous-system 17

set interfaces fe-0/0/0 unit 4 description to-A
set interfaces fe-0/0/0 unit 4 family inet address 10.10.10.10/30
set interfaces fe-0/0/1 unit 7 description to-E
set interfaces fe-0/0/1 unit 7 family inet address 10.10.10.13/30
set interfaces lo0 unit 4 family inet address 192.168.0.1/32
set protocols bgp group internal-peers type internal
set protocols bgp group internal-peers local-address 192.168.0.1
set protocols bgp group internal-peers export send-ospf
set protocols bgp group internal-peers neighbor 192.168.6.5
set protocols bgp group internal-peers neighbor 192.168.5.5
set protocols ospf area 0.0.0.0 interface lo0.4 passive
set protocols ospf area 0.0.0.0 interface fe-0/0/0.4
set protocols ospf area 0.0.0.0 interface fe-0/0/1.7
set policy-options policy-statement send-ospf term 2 from protocol ospf
set policy-options policy-statement send-ospf term 2 then accept
set routing-options router-id 192.168.0.1
set routing-options autonomous-system 17

这是他们之间没有区别的。那么，为什么它形成了上层拓扑集群呢？

我的意思是，如果路由器B想成为集群的客户端，它不应该配置更多的信息吗？

Answer 1

它就在图表的上方：

设备D和设备E被认为是非客户端，因为它们彼此显式地配置了对等关系。若要使它们成为RRroute反射器客户端，请从设备D上的配置中删除邻居192.168.5.5语句，并从设备E上的配置中删除邻居192.168.0.1语句。

在Cisco世界中，路由反射器客户机是在路由反射器上定义的，而不是在客户端上定义的。
