Special Area of OSPF summary

One, topology map

Ii. purpose of the experiment

Observe the routing of stub areas and Nssa areas and how default routes are generated

Note: Do not start R1 and R2, start other routers

Third, the experimental steps

STUB:

1. Configure the AREA1 into stub areas, see Configuration of stub areas and generation of LSA and default routes

Configure RIP redistribution to OSPF110 on the R7

router OSPF 110

Redistribute RIP subnets

Looking at the routing table on the R5, the results show that there are routes between zones and external routes. Area is identified by O IA, external routing with O E2
