Hello Expert,
i got an issue may be you can help. i am running eigrp and ospf on R8. i did
mutual redistribution between ospf and eigrp. now i want to filter only the
following network so it will show up only in eigrp route not ospf route. but
when i did it it does not show up in ospf nor in eigrp.
here is my config
router eigrp 200
redistribute ospf 110
passive-interface default
no passive-interface Serial0/0
network 11.11.4.4 0.0.0.0
network 11.11.150.4 0.0.0.0
default-metric 100000 100 250 100 1500
no auto-summary
eigrp router-id 11.11.4.4
!
router ospf 110
router-id 11.11.4.4
log-adjacency-changes
redistribute eigrp 200 subnets
passive-interface default
no passive-interface FastEthernet0/0.14
no passive-interface Serial0/1
network 11.11.114.4 0.0.0.0 area 0
