Simple Redistribution

 

 

Objectives:

1. Configure EIGRP and OSPF for the network shown. Advertise all networks on all routers. Do not implement any summarization features for EIGRP or OSPF. Use Area 0 for the OSPF portion of the network and configure all Loopback interfaces on R3 as a point-to-point OSPF network.

2. Enable full redistribution between OSPF and EIGRP, implementing any necessary seed metrics to ensure all routers are able to see all routes. OSPF external routes should not increment their metric as they propagate the network.

3. Implement distribute-list filtering in such a way that the OSPF domain only sees odd numbered loopback networks coming from R1. Any even numbered subnet (including physical networks) should be hidden from OSPF.

4. Implement route-map filtering in such a way that the EIGRP domain does not see routes with a more specific subnet mask than /24.
