4. Distribution list application

At this point, we can see that R4 can learn the two routes 3.3.3.3Universe 32 and 13.1.1.0mm24. Here we hope that R4 can only learn the route 13.1.1.0mm24 through the distribution list.

R1 configuration

Access-list 3 permit 3.3.3.3

Router eigrp 90

Distribute-list 3 out ospf 110

At this point, R4 only learns the route 13.1.1.0 + 24.
