Thanks for those tips. But as the diagram below, can I configure it like
this:
172.16.x.x } OSPF ---172.16.1.1(s0)R1(E0)192.168.1.1----EIGRP { 192.168.x.x
R1
router ospf 1
network 172.168.1.0 0.0.0.255 area 0
passive-interface ethernet 0
redistribute eigrp 1 route-map eigrp-to-ospf
router eigrp 1
network 192.168.1.0 0.0.0.255
passive-interface serial 0
redistribute ospf 1 metric 1000 100 255 1 1500 route-map ospf-to-eigrp
no auto
route-map eigrp-to-ospf permit 10
match ip add 10
route-map ospf-to-eigrp permit 10
match ip add 20
access-list 10 permit 192.168.0.0 0.0.255.255
access-list 20 pemrit 172.16.0.0 0.0.255.255
//What if I configure prefix-list instead of access-list like below
ip prefix-list OSPF seq 5 permit 172.16.0.0/16
ip prefix-list EIGrP seq 5 permit 192.168.0.0/16
any correction or comment will be greatly appreciated.
Thanks,
