Multi Point Route Redistribution Lab
يوجد العديد من النقاط تم تغطيتها في هذا اللاب علي النحو التالي:
Lab Objectives:
1- Networks 192.168.10.0/30, 192.168.17.0 and 172.20.20.0/30 should not be advertised in OSPF domain.

2- R3 should use RIP to reach 10.10.10.0/30, no route-maps, distribute-lists or prefix-lists should be used.

R3(config-router)#distance ospf external 100 inter-area 100 intra-area 100
R3(config-router)#distance 100 10.10.10.0 0.0.0.3

3- 192.168.16.0/24 should be advertised in ospf with metric of 200 and metric type of 1.

4- Any other route redistributed in ospf should be redistributed with a metric of 5000 and type 2.
Included in question 2
5- Without redistributing ospf routes back into RIP, RIP domain routers should be able to reach any network in the ospf domain.
