I have configured a topology which contains ip sla , route map , dual natting.It work perfect but when I used route map natting the eigrp become flapping and show the error is "retry limit exceeded".
Comp_R: configured Eigrp 10 between Comp_R and Tel_isp to reach to 1.1.1.0 network on Tel_isp interface f1/0. configured ip sla on Comp_R Router to track 1.1.1.1 if down then it will revert to Zon_isp. configured natting using route map on Comp_R Router.
configuration on Comp_R Router:
Comp_R (config)#Router eigrp 10
Network 10.0.0.0
Passive-interface f0/0 //no to send update on f0/0
Configure Ip sla and track
Comp_R(config)#ip sla 10
Comp_R(config-ip-sla)#icmp-echo 1.1.1.1 source-ip 10.0.0.1
Comp_R(config-ip-sla-echo)#frequency 5
Comp_R(config-ip-sla-echo)#timeout 5000
Comp_R(config)#ip sla schedule 10 start-time now life forever
Now configure track
Comp_R(config)#track 15 ip sla 10 reachability
Comp_R(config)#ip route 0.0.0.0 0.0.0.0 10.0.0.2 track 15
Comp_R(config)#ip route 0.0.0.0 0.0.0.0 20.0.0.2 10
Configure Nat on Comp_R using route map
Comp_R(config)#int f0/0
Comp_R(config-if)#ip nat outside
Comp_R(config-if)#exit
Comp_R(config)#int f1/0
Comp_R(config-if)#ip nat outside
Comp_R(config-if)#exit
Comp_R(config)#int f2/0
Comp_R(config-if)#ip nat inside
Comp_R(config-if)#exit
Comp_R(config)#route-map natfortelisp permit 10 // route map name your choice
Comp_R(config-route-map)#match interface f0/0
Comp_R(config-route-map)#exit
Comp_R(config)#route-map natforzonisp permit 10
Comp_R(config-route-map)#match interface f1/0
Comp_R(config-route-map)#exit
Comp_R(config)#ip nat inside source route-map natfortelisp interface f0/0 overload
Comp_R(config)#ip nat insdie source route-map natforzonisp interface f1/0 overload
configuration on Tel_isp Router:
Tel_isp(config)#Router eigrp 10
Network 10.0.0.0
Network 1.1.1.0
No auto-summary
Problem create when configured route map and eigrp show the following message
Comp_R#

checking Comp_R routing table it shows:
Comp_R#sh ip eig nei
