OSPF experiment

requirement ：
1. Connect... As shown in the figure , Make a reasonable plan P Address , All routers create one each -loopback Interface 、
2.R1 Create three more interfaces IP The address is 201.1.1.1/24、201.1.2.1/24、201.1.3.1/24
R5 Create three more interfaces IP The address is 202.1.1.1/124、202.1.2.1/24、202.1.3.1/24
R7 Create three more interfaces IP The address is 203.1.1.1/124、203.1.2.1/24、203.1.3.1/24
Configure each point as shown in the figure IP Address

3. Run the routing protocol as shown in the figure
R1-R2-R3 Used between MGRE The Internet , by hub- spoke Network structure ,R1 by hub End ,
Deploy OSPF The Internet ,MGRE It is amended as follows BMA Network type



R1 And r2 r3 Build a neighborhood
R2 r3 Only with r1 Build neighbors, not each other

4.area1 The area must not appear 4.5 class LSA
Because there is also a link rip, It needs to be republished So we need nssa Area


Irregular areas Need to put are2 Extend to r2 r3 On , Hang on the backbone area




R4 r5 function rip200
5. Other regions have priority to pass R3 visit R1 Three loopback interfaces
6. Minimize the number of routing entries




7.area1 Increase security in the area
R2 r3 r4 All areas 1 Certification of



8. Network wide accessibility
