Hi all:
I have a problem with redistribution and I am hoping someone can help me
understand what is going wrong.
Basic:
If I redistribute connected in eigrp why don't my ospf networks (which are the
connected interfaces) show up in the eigrp
table when I redistribute ospf into eigrp?
To illustrate:
Lets say I have a eigrp and ospf configuration of the following:
!
router eigrp 100
redistribute connected metric 100000 20000 255 1 1500 route-map conn-eigrp
network 136.9.23.2 0.0.0.0
no auto-summary
eigrp router-id 198.9.2.2
redistribute ospf 1
default-metric 10000 100 255 1 1500
!
router ospf 1
router-id 198.9.2.2
log-adjacency-changes
auto-cost reference-bandwidth 20000
redistribute eigrp 100 metric-type 1 subnets route-map eigrp-ospf
network 136.9.245.2 0.0.0.0 area 0
network 198.9.2.2 0.0.0.0 area 0
distance 171 198.9.1.1 0.0.0.0 1
I see within the ospf domain my loopback of 198.9.2.2 as well as the
136.9.245.2. Now I look too see what the eigrp topology table looks like. sh
ip ei top 198.9.2.0 255.255.255.0 (since this is a /24 w/ospf network P-T-P
under the loopback). I do not see the route. Now I remove the redistributed
connected from the eigrp process. I do a sh ip ei top 198.9.2.0 255.255.255.0
and the route is there now.
My question, why is eigrp blocking the redistributed route only when I have
redistributed connected with the route-map. If I remove the route-map I see the
route, but it's not coming from the ospf process, but from the redistributed
process. If I remove the redist connected I see the route, but this is not what
I want.
The system is filtering where it shouldn't, it's filting routes coming from the
ospf process AND the connected.
Ideas?
