![Practice Lab 1---NBMA环境中OSPF的应用_路由](https://s2.51cto.com/attachment/200704/200704161176720114671.jpg?x-oss-process=image/resize,m_fixed,w_1184)
2. Put R1’s ethernet 0 in area 1
3. Put R2’s ethernet 0 in area 10
4. Put R3’s serial 1 and all of R4 in area 3
5. Put R5’s ethernet 0 in area 4.
6. Create two loopback interfaces on R4 and put both of the associated subnets on R4 in area 44.
7. Summarize the 2-loopback subnets so they appear as one route to the rest of the OSPF routers.
8. Here is tricky part; You can’t use the command ip ospf network anywhere in your
configurations.
9. As stated before you should be able to ping every interface from any router.
10. Redistribute the default route on R2 as type-1 with a metric of 100.
