Question on Reliable IP Route

Just found out about this IOS feature quite recently and I do have a question about it...

In a scenario such as below:



R1-------| LAN



I would typically have two default-routes configured on R1 performing load-balancing:

ip route

ip route

Can I use IP SLA to track both static routes, removing one if it has failed? How?

The alternative is of course to run BGP with the ISPs. But the extra complexity and expense might be too much overkill. The end user simply wants load-balancing and redundancy for web browsing only.

Possible using Object Tracking

Follow-up question:

The doc states that: "This feature is supported in all Cisco IOS software images for the Cisco 1700 series modular access routers except the Cisco IOS IP Base image."

So, will it work on the ISRs? (2800, 3800, etc)?

Re: Question on Reliable IP Route


what is the link you are using to connect to ISP. if its a serial link the ip route which you are giving will go off if the link goes down and the traffic will take the secondary link. This reliable static routes will help you in connections to the ISP like a DSL,Metro Ethernet in these cases if the switched network in the service provider fails you will see the local link up and will create a black hole for the static route as there are no keep alive mechanism for a static route. In this scenario we will have the SAA feature to help us.

I hope my reply has clarified your query.

Thanks and Regards,
