Static to Eigrp Redistribution

[adriangreniergarcia]

Dear,

I am creating this discution to confirm if a distribution from Static to Eigrp would work properly in the following scenario.

I have two static routes in my Core Switch

ip route 192.168.229.0/24 192.168.142.44

ip route 192.168.229.0/24 192.168.142.43 metric 10

Basically I have two FTD (192.168.142.44 and 192.168.142.43) working as standby and the route with the metric 10 has just the purpose to be active in case we lost 192.168.142.44.

Question: If I redistribute to Eigrp, are both routes going to be redistributed?

Redistribution config:

prefix-list WHITE-PREFIX seq 1 permit 192.168..229.0/24 le 32

!

route-map WHITENET permit 1

match ip address prefix-list WHITE-PREFIX

EIGRP 100

redistribute static metric 1000 1000000 1 255 1500 route-map WHITENET

No they won’t be, Only the active route in the route table will be advertised, the way you would need to do this would to conditionally advertise the static routes, as such as when you lose the primary static the secondary would get advertised.

Example:
ip sla 1
icmp-echo 192.168.142.44 source-ip x.x.x.x
ip sla schedule 1 life forever start-time now
track 1 rtr 1 reachability
ip route 192.168.229.0 255.255.255.0 192.168.142.44 track 1
ip route 192.168.229.0 255.255.255.0 192.168.142.43 10

The only other thing i can surmise from your OP is that those static next-hops suggest they route through the same interface which would possibly make those next-hop ip's recursive so may not be part of a connected interface on the core switch, Can you confirm this please.

Thanks Paul, your explanation was exactly what I needed to understand the the scenario,

 I know this issue solve, but I ask why you want to advertise both static route?

the Core SW will redirect the traffic to next-hop, other hop behind the Core SW will not effect, but I want to know why you ask ?
