The third step ： because P2P Type is unable to establish neighbor relationship with other routes , You need to change MGRE type    --- P2MP type .

area4 Areas and rip Missing routing information between regions , We need to import manually by republishing rip Routing and area4 Routing information for

[R9-ospf-1]import-route ospf 2

R10 There will be no other routing information , At this time, we can send a default route to our R9

[R9]ospf 2
[R9-ospf-2]default-route-advertise

Step four ： In order to reduce the LSA Update quantity of , We need to do summary and special areas
Be careful ： In order to avoid loops, we also need to configure empty interface routes .

  Step six ： Speed up convergence , Need to change HELLO Time , To change the hello The time of death will also change automatically .

To build neighborhoods , take hello Other routers in the time zone are changed to consistent .
