I have now reproduced this from scratch, using different router models in GNS3. As mentioned before this works fine in OSPF, but does not work in EIGRP.
i have removed all complications, and i am now simply redistributing a static route to null0 on one side of the network. At the other, a floating static route to the same address via null0 with an AD of 210.
when the remote route is removed, the floating static enters the routing table. when it is re-added remotely, the floating static is not removed.
Heres the weird thing. If i do this on a chain of two routers, it works perfectly. if i extend the chain to three routers, it doesn't. configs pasted. R1 left hand router where routes are added and removed. R0 middle router. R2 left hand router with floating static. just in case any one can reproduce for me.. :) thanks config ! version 12.4 service timestamps debug datetime msec service timestamps log datetime msec no service password-encryption ! hostname R1 ! boot-start-marker boot-end-marker ! ! no aaa new-model memory-size iomem 15 ip cef ! ! ! ! ! ! ! ! ! ! ! interface FastEthernet0/0 ip address 10.10.10.10 255.255.255.0 duplex auto speed auto ! interface FastEthernet0/1 no ip address shutdown duplex auto speed auto ! router eigrp 1 redistribute static network 10.10.10.0 0.0.0.255 no auto-summary ! ip forward-protocol nd ip route 45.45.45.45 255.255.255.255 Null0 ! ip http server no ip http secure-server ! ! control-plane ! ! line con 0 line aux 0 line vty 0 4 login ! ! end ! version 12.4 service timestamps debug datetime msec service timestamps log datetime msec no service password-encryption ! hostname R0 ! boot-start-marker boot-end-marker ! ! no aaa new-model memory-size iomem 15 ip cef ! ! ! ! ! ! ! ! ! ! ! interface FastEthernet0/0 ip address 10.10.10.1 255.255.255.0 duplex auto speed auto ! interface FastEthernet0/1 ip address 20.20.20.2 255.255.255.0 duplex auto speed auto ! router eigrp 1 redistribute static network 10.10.10.0 0.0.0.255 network 20.20.20.0 0.0.0.255 no auto-summary ! ip forward-protocol nd ip route 55.55.55.55 255.255.255.255 Null0 ! ip http server no ip http secure-server ! ! control-plane ! ! line con 0 line aux 0 line vty 0 4 login ! ! end ! version 12.4 service timestamps debug datetime msec service timestamps log datetime msec no service password-encryption ! hostname R2 ! boot-start-marker boot-end-marker ! ! no aaa new-model memory-size iomem 15 ip cef ! ! ! ! ! ! ! ! ! ! ! interface FastEthernet0/0 ip address 20.20.20.20 255.255.255.0 duplex auto speed auto ! interface FastEthernet0/1 no ip address shutdown duplex auto speed auto ! router eigrp 1 redistribute static network 20.20.20.0 0.0.0.255 no auto-summary ! ip forward-protocol nd ip route 45.45.45.45 255.255.255.255 Null0 210 ip route 55.55.55.55 255.255.255.255 Null0 210 ! ip http server no ip http secure-server ! ! control-plane ! ! line con 0 line aux 0 line vty 0 4 login ! ! end
