Advanced Redistribution

—————————-
Router 1 – OSPF
—————————-

config
router ospf 1
network 10.0.0.0 0.255.255.255 area 0
—————————-
Router 2 – Redistibution point
—————————-

– basic config

config t
router ospf 1
netwrok 10.1.12.0 0.0.0.255 area 0

config t
router eigrp 100
network 10.1.24.0 0.0.0.255
network 10.1.23.0 0.0.0.255
no auto

– Redistribution EIGRP to OSPF

1) match criteria

access-list 1 permit 10.4.0.0 0.0.0.255
access-list 1 permit 10.4.1.0 0.0.0.255

access-list 2 permit 10.4.2.0 0.0.0.255
access-list 2 permit 10.4.3.0 0.0.0.255

access-list 3 permit 10.4.4.0 0.0.0.255

2) Route map

route-map EIGRP-TO-OSPF 10
match ip address 1
set metric 100
set tag 10

route-map EIGRP-TO-OSPF 20
match ip address 2
set metric 200
set tag 20

route-map EIGRP-TO-OSPF deny 30 (deny a access list)
match ip address 3

route-map EIGRP-TO-OSPF 40 ( this is a match all)
set metric 300
set tag 30

verify

show route-map

show ip route 10.4.2.0

3) Applying

config t
router ospf 1
redistribute eigrp 100 subnets route-map EIGRP-to-OSPF

– Redistribution OSPF to EIGRP

config t
router-map OSPF-TO-EIGRP
set metric 400 20 255 1 1500
set tag 40

router eigrp 100
redistribute ospf 1 route-map OSPF-to-EIGRP

– Preventing loops with redundancy equipments

EIGRP to OSPF

show route-map

route-map EIGRP-TO-OSPF deny 5
match tag 40

OSPF to EIGRP

route-map OSPF-TO-EIGRP deny
match 10 20 30 (10 or 20 or 30)
