Ip sla schedule 1 life forever start-time now Track, IP SLA and Default Route Configurations. Interface Configurations interface GigabitEthernet0/0/1 For test purposes, use the IP address 10.10.10.10 as a reference to Internet. ISP 1 and ISP 2 directly connect to the Internet. If the network is live, make sure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment. It applies to all Cisco routers that run Cisco IOS and where IP SLA and Track can be configured. This document is not restricted to specific software and hardware versions. There are no specific requirements for this document. Basic understanding of creating IP SLA and Static Routing.Configuration of IP SLA must be supported on the device and platform. when Primary ISP goes down then Secondary takes over with correct NAT with the use of the secondary ISP's public IP address. This document also explains how to configure Network Address Translation (NAT) when there are multiple ISP's for internet connectivity and you want seamless failover i.e. This document describes how to configure WAN (or ISP) redundancies, wherein multiple WAN links terminate on the same end router.
