Hello group!
I've got following simple topology:
Sw1 -----vlan10---- f0/0 R3 s0/0
(svi) |
|---------f0/0 R4 s0/0
EIGRP: f0/0@R3,R4, SVI on Sw1, OSPF - on s0/0@R3,R4
I'm doing mutual redistribution on R3 and R4 :
CCIE-R4#sh run | be router
router eigrp 1
redistribute ospf 1 metric 1000 100 255 1 1500
network 1.1.4.4 0.0.0.0
network 1.1.10.4 0.0.0.0
no auto-summary
!
router ospf 1
router-id 1.1.4.4
log-adjacency-changes
redistribute eigrp 1 subnets
network 1.1.4.4 0.0.0.0 area 0
network 1.1.11.4 0.0.0.0 area 0
CCIE-R3#sh run | be router
router eigrp 1
redistribute ospf 1 metric 1000 100 255 1 1500
network 1.1.3.3 0.0.0.0
network 1.1.10.3 0.0.0.0
no auto-summary
!
router ospf 1
router-id 1.1.3.3
log-adjacency-changes
redistribute eigrp 1 subnets
network 1.1.3.3 0.0.0.0 area 0
network 1.1.11.3 0.0.0.0 area 0
And on Sw1 I have 2 routes to 1.1.11.0/24. - simple
CCIE-SW1#sir 1.1.11.1
Routing entry for 1.1.11.0/29
Known via "eigrp 1", distance 170, metric 2585856, type external

BUT...
When I add some loopback on R4: lo5 on R4
interface Loopback5
ip address 5.5.5.5 255.255.255.255
end
And try to redistribute it to EIGRP through simple route-map as connected:
CCIE-R4#sh route-map CONN
route-map CONN, permit, sequence 10
Match clauses:
interface Loopback5
Set clauses:
Policy routing matches: 0 packets, 0 bytes
And add this string to R3 config under EIGRP: redistribute connected metric
1000 100 255 1 1500 route-map CONN
on Sw1 one route to 1.1.11.0/24 removed from RIB
CCIE-SW1#sir 1.1.11.1

At that moment I have "debug eigrp fsm" on Sw1:
