网络工程 - OSPF 配置：路由器 ID 不会更改为环回地址 - 吾爱随笔录

我是新手，所以请原谅我的错误，但我觉得我在这里遗漏了一些东西。

我正在尝试使用环回地址作为我网络中 Router0 的路由器 ID。我正在输入：

Router(config)#int loopback 0
Router(config-if)#ip address 1.1.1.1 255.255.255.255
Router(config-if)#
Router(config-if)#exit
Router(config)#do show ip int brief
Interface              IP-Address      OK? Method Status                Protocol 
FastEthernet0/0        150.45.101.1    YES manual up                    up 
FastEthernet1/0        unassigned      YES unset  administratively down down 
Serial2/0              200.200.200.3   YES manual up                    up 
Serial3/0              unassigned      YES unset  administratively down down 
FastEthernet4/0        unassigned      YES unset  administratively down down 
FastEthernet5/0        unassigned      YES unset  administratively down down 
Loopback0              1.1.1.1         YES manual up                    up
Router(config)#

所以我们可以看到已经配置了环回，但是当我显示路由器 ID 时，它仍然显示串行接口作为它的 ID。

Router(config)#do show ip ospf
 Routing Process "ospf 100" with ID 200.200.200.3
Supports only single TOS(TOS0) routes
 Supports opaque LSA
 It is an area border router
 SPF schedule delay 5 secs, Hold time between two SPFs 10 secs
 Minimum LSA interval 5 secs. Minimum LSA arrival 1 secs
 Number of external LSA 0. Checksum Sum 0x000000
 Number of opaque AS LSA 0. Checksum Sum 0x000000
 Number of DCbitless external and opaque AS LSA 0
 Number of DoNotAge external and opaque AS LSA 0
 Number of areas in this router is 2. 2 normal 0 stub 0 nssa
 External flood list length 0
    Area BACKBONE(0) (Inactive)
        Number of interfaces in this area is 0
        Area has no authentication
        SPF algorithm executed 5 times
        Area ranges are
        Number of LSA 2. Checksum Sum 0x0137ce
        Number of opaque link LSA 0. Checksum Sum 0x000000
        Number of DCbitless LSA 0
        Number of indication LSA 0
        Number of DoNotAge LSA 0
        Flood list length 0
    Area 1
        Number of interfaces in this area is 1
        Area has no authentication
        SPF algorithm executed 2 times
        Area ranges are
        Number of LSA 0. Checksum Sum 0x000000
        Number of opaque link LSA 0. Checksum Sum 0x000000
        Number of DCbitless LSA 0
        Number of indication LSA 0
        Number of DoNotAge LSA 0
        Flood list length 0

为了解决这个问题，我试过这个：

Router(config)#do clear ip ospf process
Reset ALL OSPF processes? [no]: y
Router(config)#

但是当我再次运行这个命令时，我得到了相同的结果：

Router(config)#do show ip ospf
 Routing Process "ospf 100" with ID 200.200.200.3
Supports only single TOS(TOS0) routes
 Supports opaque LSA
 It is an area border router

 Number of opaque AS LSA 0. Checksum Sum 0x000000
 Number of DCbitless external and opaque AS LSA 0
 Number of DoNotAge external and opaque AS LSA 0
 Number of areas in this router is 2. 2 normal 0 stub 0 nssa
 External flood list length 0
    Area BACKBONE(0) (Inactive)
        Number of interfaces in this area is 0
        Area has no authentication
        SPF algorithm executed 5 times
        Area ranges are
        Number of LSA 2. Checksum Sum 0x0137ce
        Number of opaque link LSA 0. Checksum Sum 0x000000
        Number of DCbitless LSA 0
        Number of indication LSA 0
        Number of DoNotAge LSA 0
        Flood list length 0
    Area 1
        Number of interfaces in this area is 1
        Area has no authentication
        SPF algorithm executed 2 times
        Area ranges are
        Number of LSA 0. Checksum Sum 0x000000
        Number of opaque link LSA 0. Checksum Sum 0x000000
        Number of DCbitless LSA 0
        Number of indication LSA 0
        Number of DoNotAge LSA 0
        Flood list length 0

这是运行配置：

Router(config-if)#do show running-config

我们可以看到路由器 ID 没有改变，我在这里做错了什么？
