该博客围绕网络实验展开，介绍了网络配置过程。先配置星型结构，为r1、r2、r3配置gre协议，修改优先级放弃竞选DR；再为r1、r4、r5配置MGRE结构，封装接口协议。完成后可相互学习路由，实现全网可达，同时给出检查直连和静态可达等注意事项。

直连可达

[r1]ip route-static 0.0.0.0 0 10.0.0.2
[r1]ip route-static 0.0.0.0 0 20.0.0.2

[r2]ip route-static 0.0.0.0 0 30.0.0.2

[r3]ip route-static 0.0.0.0 0 40.0.0.2

[r4]ip route-static 0.0.0.0 0 50.0.0.2

[r5]ip route-static 0.0.0.0 0 60.0.0.2

达到可达

1.首先配置星型结构，给r1,r2,r3配置gre协议

配置tunnel接口

[r1-Tunnel0/0/0]dis th
[V200R003C00]
#
interface Tunnel0/0/0
 ip address 10.1.2.1 255.255.255.0 
 tunnel-protocol gre p2mp
 source 20.0.0.1
 nhrp entry multicast dynamic

[r2]display nhrp peer a
------------------------------------------------------------------------------- 
Protocol-addr   Mask  NBMA-addr       NextHop-addr    Type         Flag         
------------------------------------------------------------------------------- 
10.1.2.1        32    20.0.0.1        10.1.2.1        static       hub          
------------------------------------------------------------------------------- 
Tunnel interface: Tunnel0/0/0
Created time    : 00:01:09
Expire time     : --

[r1]display nhrp peer a
------------------------------------------------------------------------------- 
Protocol-addr   Mask  NBMA-addr       NextHop-addr    Type         Flag         
------------------------------------------------------------------------------- 
10.1.2.2        32    30.0.0.1        10.1.2.2        dynamic      route tunnel 
------------------------------------------------------------------------------- 
Tunnel interface: Tunnel0/0/0
Created time    : 00:03:34
Expire time     : 01:56:26
------------------------------------------------------------------------------- 
Protocol-addr   Mask  NBMA-addr       NextHop-addr    Type         Flag         
------------------------------------------------------------------------------- 
10.1.2.3        32    40.0.0.1        10.1.2.3        dynamic      route tunnel 
------------------------------------------------------------------------------- 
Tunnel interface: Tunnel0/0/0
Created time    : 00:00:38
Expire time     : 01:59:22

Number of nhrp peers: 2

修改优先级放弃竞选DR


[r2-Tunnel0/0/0]ospf dr-priority 0

[r3-Tunnel0/0/0]ospf dr-priority 0

r1,r2,r3之间建立完

[r1]display ospf peer brief 

	 OSPF Process 1 with Router ID 1.1.1.1
		  Peer Statistic Information
 ----------------------------------------------------------------------------
 Area Id          Interface                        Neighbor id      State    
 0.0.0.0          Tunnel0/0/0                      2.2.2.2          Full        
 0.0.0.0          Tunnel0/0/0                      3.3.3.3          Full        
 ----------------------------------------------------------------------------

2.配置r1,r4,r5配置MGRE结构

同上先配置Tunnel接口地址

[r5-Tunnel0/0/0]ip address 10.1.1.5 24

[r4-Tunnel0/0/0]ip address 10.1.1.4 24

封装接口协议

[r4-Tunnel0/0/0]tunnel-protocol gre p2mp

[r5-Tunnel0/0/0]tunnel-protocol gre p2mp

[r4-Tunnel0/0/0]source GigabitEthernet 0/0/0

[r4-Tunnel0/0/0]nhrp entry 10.1.1.1 10.0.0.1 register

[r4-Tunnel0/0/0]ospf network-type broadcast

查看nhrp相关信息

[r1]display nhrp peer all 
------------------------------------------------------------------------------- 
Protocol-addr   Mask  NBMA-addr       NextHop-addr    Type         Flag         
------------------------------------------------------------------------------- 
10.1.2.2        32    30.0.0.1        10.1.2.2        dynamic      route tunnel 
------------------------------------------------------------------------------- 
Tunnel interface: Tunnel0/0/0
Created time    : 01:08:53
Expire time     : 01:51:07
------------------------------------------------------------------------------- 
Protocol-addr   Mask  NBMA-addr       NextHop-addr    Type         Flag         
------------------------------------------------------------------------------- 
10.1.2.3        32    40.0.0.1        10.1.2.3        dynamic      route tunnel 
------------------------------------------------------------------------------- 
Tunnel interface: Tunnel0/0/0

Expire time     : 01:54:03
------------------------------------------------------------------------------- 
Protocol-addr   Mask  NBMA-addr       NextHop-addr    Type         Flag         
------------------------------------------------------------------------------- 
10.1.1.5        32    60.0.0.1        10.1.1.5        static       hub          
-------------------------------------------------------------------------------

------------------------------------------------------------------------------- 
10.1.1.4        32    50.0.0.1        10.1.1.4        static       hub          
------------------------------------------------------------------------------- 
Tunnel interface: Tunnel0/0/1
Created time    : 00:47:05
Expire time     : --

两个静态，两个hub,ospf搭建完成，可以相互学习路由，全网可达

[r1]display ip routing-table protocol ospf 
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Public routing table : OSPF
         Destinations : 4        Routes : 4        

OSPF routing table status : <Active>
         Destinations : 4        Routes : 4

Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface

    192.168.2.1/32  OSPF    10   1562        D   10.1.2.2        Tunnel0/0/0
    192.168.3.1/32  OSPF    10   1562        D   10.1.2.3        Tunnel0/0/0
    192.168.4.1/32  OSPF    10   1562        D   10.1.1.4        Tunnel0/0/1
    192.168.5.1/32  OSPF    10   1562        D   10.1.1.5        Tunnel0/0/1

[r4]display current-configuration interface t 0/0/0
[V200R003C00]
#
interface Tunnel0/0/0
 ip address 10.1.1.4 255.255.255.0 
 tunnel-protocol gre p2mp
 source GigabitEthernet0/0/0
 ospf network-type broadcast
 nhrp entry 10.1.1.5 60.0.0.1 register
 nhrp entry 10.1.1.1 10.0.0.1 register
#
return

注意事项：

先要检查直连和静态可达

记得需要重启tunnel接口，建立邻居

p2p是点到点协议，需要需修改接口类型broadcast
