How to configure EIGRP OSPF Redistribution:
Step 1: Configure IP and Routing of all routers (Lab topology and Running configuration below)
Step 2: Check out Metric of interfaces using command # show ip interface
R2#show interfaces s0/0/0
Bandwidth=1544 Kbit
Delay=20000/10=2000 > delay 20000 / delay always divided by 10 = 2000
Reliability=255
Load= 1
MTU=1500 bytes
R3#show interfaces f0/0
Bandwidth=100000 Kbit
Delay=100/10=10 > delay 20000 / delay always divided by 10 = 10
Reliability=255
Load=1
MTU=1500 bytes
Step 3:
R2 Router Configuration:
R2(config)#router ospf 1
R2(config-router)#redistribute eigrp 100 metric-type 1 subnets OR
R2(config-router)#redistribute eigrp 100 subnets
R2(config)#router eigrp 100
R2(config-router)#redistribute ospf 1 metric 1544 2000 255 1 1500
R3 Router Configuration:
R3(config)#router ospf 1
R3(config-router)#redistribute eigrp 100 metric-type 1 subnets OR
R3(config-router)#redistribute eigrp 100 subnets
R3(config)#router eigrp 100
R3(config-router)#redistribute ospf 1 metric 100000 10 255 1 1500
