EIGRP and OSPF route redistribution

EIGRP and OSPF route redistribution LAB

R2 is an ASBR for EIGRP 100 and OSPF area 24
R3 is an ASBR for EIGRP 100 and OSPF area 34
R1 is only EIGRP 100
Notice : you should make a ping from R1 to R5  IP:172.16.100.1

Answer command :

R2#
R2(config)#router ospf 1
R2(config-router)#redistribute eigrp 100 metric-type 1 subnets
R2(config-router)#exit
R2(config)#router eigrp 100
R2(config-router)#redistribute ospf 1 metric 1544 200 255 1 1500
R2(config-router)#end
R2#


R3(config)#router ospf 1
R3(config-router)#redistribute eigrp 100 metric-type 1 subnets
R3(config-router)#exit
R3(config)#
R3(config)#router eig 100
R3(config-router)#redistribute ospf 1 metric 10000 100 255 1 1500
R3(config-router)#end
R3#

Before redistribution , show ip route
=================================

R5#sh ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

     172.16.0.0/24 is subnetted, 1 subnets
C       172.16.100.0 is directly connected, FastEthernet0/0
O IA 192.168.4.0/24 [110/11] via 172.16.100.4, 00:02:58, FastEthernet0/0
O IA 192.168.3.0/24 [110/74] via 172.16.100.4, 00:02:58, FastEthernet0/0
