1, illustrating the configuration in accordance with an IP address, the gateway point PC1 is R8
2, the OSPF is divided into four regions, wherein 192.168.0.0/24,192.168.1.0/24,192.168.2.0/24 belonging AREA 0,192.168.10.0 / 24 belongs AREA1,192.168.4.0 / 24,100.0.0.0 / 24 belonging AREA2,192.168.5.0,100.1.1.0 / 24 belongs to AREA3
. 3, in order to prevent link break due to the backbone spacer, disposed in the virtual connection R3 and R4
4, arranged on the static route R5 and 172.16.0.0/24 172.16.1.0/24 segment, and introduced into the interior of OSPF
5, configure a default route on R7 and R8, R5 and next hop point R6
. 6, in on the ASBR of 172.16.1.0/24 172.16.0.0/24 and accurate route aggregation network
7, respectively aREA segment is 0 and R3 and R4 on the polymerization route
8, will be configured as an NSSA area AREA3
9, the R6 static route configuration 100.2.2.0/24 segment, and introduced into AREA3
10, in the authentication area AREA0 configuration, the password is 123456
