 nhrp entry 192.168.6.1 16.0.0.1 register  --- Find a registration center

Four ,R1/4/5 For the whole company MGRE structure , Mutual center and branch .
1, stay R1 On the configuration

 interface Tunnel0/0/1

 tunnel-protocol gre p2mp
 source 61.0.0.1
 nhrp network-id 200
 nhrp entry 192.168.7.2 46.0.0.1 register --- look for r4 register
 nhrp entry 192.168.7.3 56.0.0.1 register --- look for r5 register
 nhrp entry multicast dynamic 

2, stay R4 On the configuration

 interface Tunnel0/0/1
 ip address 192.168.7.2 255.255.255.0 
 tunnel-protocol gre p2mp
 source 46.0.0.1
 nhrp entry multicast dynamic
 nhrp network-id 100
 nhrp entry 192.168.7.2 56.0.0.1 register --- look for r5 register
        --- Keep looking r1 To register ,

3, stay R5 On the configuration

 interface Tunnel0/0/1
 ip address 192.168.7.3 255.255.255.0 
 tunnel-protocol gre p2mp
 source 56.0.0.1
 ospf network-type broadcast
 nhrp entry multicast dynamic
 nhrp network-id 100
     ---r1 and r4 Already registered , Because registration is two-way

5、 ... and , Use osfp agreement

r1:

  ospf 1 router-id 1.1.1.1 
  area 0.0.0.0 
  network 192.168.1.0 0.0.0.255 
  network 192.168.6.0 0.0.0.255 
  network 192.168.7.0 0.0.0.255 

r2:

ospf 1 router-id 2.2.2.2
 area 0.0.0.0 
  network 192.168.2.0 0.0.0.255 
  network 192.168.6.0 0.0.0.255 

r3:

  ospf 1 router-id 3.3.3.3
  area 0.0.0.0 
  network 192.168.3.0 0.0.0.255 
  network 192.168.6.0 0.0.0.255 

r4;

ospf 1 router-id 4.4.4.4 
 area 0.0.0.0 
  network 192.168.4.0 0.0.0.255 
  network 192.168.7.0 0.0.0.255 

r5:

ospf 1 router-id 5.5.5.5
 area 0.0.0.0 
  network 192.168.5.0 0.0.0.255 
  network 192.168.7.0 0.0.0.255 

Modify the network type for the virtual interface

 [r1-Tunnel0/0/0]ospf network-type broadcast   
 [r1-Tunnel0/0/1]ospf network-type broadcast
 [r4-Tunnel0/0/1]ospf network-type broadcast
 [r5-Tunnel0/0/1]ospf network-type broadcast
 [r2-Tunnel0/0/0]ospf network-type broadcast
 [r3-Tunnel0/0/0]ospf network-type broadcast 

because R2 and R3 Different cognition of , So it needs to be abandoned , Change the priority to 0
[r3-Tunnel0/0/0]ospf dr-priority 0
[r2-Tunnel0/0/0]ospf dr-priority 0

because R1 ,R4, R5 They are branches and centers of each other , Will automatically select DR and BDR.

6、 ... and , Network wide accessibility
