1.6 Redistribution - Routing path between RIP and OSPF through EIGRP
To match the "R3#show ip route rip | begin Gateway" and "R4#show ip route rip | begin Gateway" output the following config lines have to be added to ensure that routes between the RIP and OSPF routing domains are not exchanged via the EIGRP routing domain. For the task requirements it is not a must.
route-map EIGRP_INTO_OSPF_REDISTRIBUTION deny 5
match tag 590
route-map EIGRP_INTO_RIP_REDISTRIBUTION deny 5
match tag 190
